Anedio D2 DAC
http://www.anedio.com/index.php/product/d2_overview

Price: $1470.00

32-bit DAC

At the center of the Anedio D2 is the ES9018 Sabre Reference 32-bit DAC from ESS Technologies. Its oversampling modulator, optimized for accurate reproduction of music, excels at maintaining superb linearity at all levels, tracking fast transients. and resolving lowermost signals. You will be able to hear minute details, accurate rendition of instrumental timbres, and spatial cues from reverberations.
Multi-Stage Jitter Reduction

The D2 DAC incorporates multi-stage jitter reduction circuits to tame jitter as far as possible, well below the threshold of audibility. As the digital signal goes through each stage, the jitter level is progressively reduced until the critical final stage, which is driven by an ultra-low jitter oscillator with 0.5 ps rms jitter. Whether you listen to music through USB or SPDIF, the multi-stage jitter reduction is highly effective, delivering consistently natural, musical, and relaxed sound. Read "Multi-Stage Jitter Reduction"
Bit-Accurate Jitter Reduction

Conventional jitter reduction schemes modify every sample based on a constantly-changing estimate of the input sample rate, inevitably introducing audible artifacts. By contrast, the Anedio D2 preserves the original samples in their pristine condition through the jitter reduction stages. Only at the final stage of the ES9018 DAC, time-domain interpolation is performed at a much higher frequency, which suppresses interpolation errors to below -175 dB.
Built-in Volume Control

The built-in volume control allows power amplifiers to be connected directly to the D2 DAC, eliminating the preamp in the signal path when playing from a digital source. Bypassing the preamp is one of the most significant steps toward a higher level of transparency. To ensure highest signal-to-noise ratios at realistic listening levels, our design uses an optimal combination of 32-bit digital attenuators and thin-film resistor dividers.
High-Resolution 24-bit/192 KHz USB

From the Red Book CD to the 24-bit/192 KHz format, the USB interface of the D2 will transform the computer into a pristine, jitter-free source of music. The USB interface controls its own timing (the asynchronous mode) using low-jitter crystal oscillators, and the real-time XMOS processor ensures the fine control of timing required for asynchronous streaming.
Balanced and Unbalanced Outputs

The D2 DAC offers both balanced and unbalanced line outputs. The balanced output is as pristine as it can get, fully preserving the differential path from the DAC chip to the output with minimal circuitry. Both balanced and unbalanced outputs are carefully optimized to bring out the dynamic impact, immediacy, and natural timbre of music
High-Performance Headphone Amplifier

Equipped with a high-current buffer, the headphone amplifier can drive just about any headphones easily and accurately. Our ultra-linear design achieves lower than 0.0004% THD+N and 0.0002% IMD2 (19K+20KHz) driving 30 ohm loads. Its low-impedance output guarantees that the distortion will be kept absolutely minimal regardless of the nonlinearity of the headphone impedance.
IR Remote Control

The D2 DAC comes with a Sony universal IR remote control for setting the volume level and channel. With extra large buttons and comfortable ergonomic design, the IR remote is simple and easy to use. As with most people, we do not like to pile up remote controls in our living rooms. In case you want to use another universal remote to control the Anedio D2 DAC, we've made it easy to do so by using a common IR protocol that is readily recognized by most universal remote controls.
Galvanic Isolation

The four digital inputs (USB, SPDIF 75-ohm BNC, RCA, and optical) are completely isolated from the DAC ground to ensure that the noise from other digital sources does not propagate into the DAC ground. Ultra-high-frequency digital transformers used in the D2 DAC excel at isolating the ground while passing on the digital signal with high fidelity.
Read more . . .
Channel Separation

Through extensive optimization of the PCB layout and judicious use of separate voltage regulators, the D2 DAC achieves near perfect channel separation, -140dB at 1KHz and -135dB at 20KHz. With good recordings, the sense of space can really blossom, and the music becomes more alive with the clarity of focus, the stability of imaging, and the depth and width of soundstage.
Premium-Quality Components

Every part of the D2 DAC is touched by our joy of building a quality product. You will find premium-quality components used abundantly throughout the D2 DAC -- 4-layer PCBs, ultra-high-frequency digital transformers, gold-plated connectors, toroidal power transformers with magnetic shields, low-noise voltage regulators, fast-settling op amps, 0.5% precision film resistors, SiC Schottky diodes, and high-reliability supply capacitors.
Solid Non-Ferromagnetic Chassis

All of this is packaged in a non-ferromagnetic enclosure for enhanced immunity to electromagnetic interference and high-frequency noise, which contributes to an extremely low noise floor. The faceplate is machined from a 0.32 inch thick aluminum block, which forms a mechanically rigid structure with the rest of the enclosure and makes the DAC impervious to acoustically-induced vibrations.

The Trinity preamplifier/DAC has the distinction of being one of the most expensive product of its kind in the world (42,000 Euros or $57,950 at today’s exchange rate; the price is the same worldwide), but this is no boutique product aimed at the status-conscious elite. Rather, it is simply the realization of what Brauer believes is the ultimate DAC topology. For starters, the three-chassis Trinity DAC employs 16 Burr-Brown PCM 1704 DACs per channel that are driven by a time-interleaved signal. That is, each DAC is driven by an input signal that has been delayed slightly in relation to the preceding DAC. The DAC outputs are all switched together, resulting in an analog output waveform in which the classic stair-step structure is much finer, smoother, and closer in shape to the original sine wave. In fact, the waveform is so smooth that the Trinity DAC allows you to bypass the digital filter entirely when playing high-resolution sources (three selectable filters are available for standard-resolution sources). The measurements presented in the brochure are the best I’ve seen on any DAC.

Also wenn der Hersteller meint, dass das ein Problem des Verstärkers ist, aber nicht ein Problem fast jeder zweiten CD, dann frage ich mal laut, warum das Thema Polarität von Aufnahmen schon mehr als 25 Jahre bekannt ist, aber bei solchen Hochpreisanbietern noch nicht angekommen ist. Im Digitalbereich ist der Polaritätswechsel wohl mit den geringsten Nebenwirkungen zu vollziehen.

Der Zugewinn an Präzision, Deutlichkeit, Fokus und Vorn-Hintenstaffelung ist mehr wert, als 20 Sekunden Verweildauer am Gerät. Die sind natürlich völlig übertrieben, 2 Sekunden müssten ausreichend sein, aber bitte fernbedienbar obendrein...

The Leema Elements DAC is the first stand-alone Leema DAC and as such establishes the Leema benchmark for digital-to-analogue conversion, in performance as well as features.

Quattro DAC topology, derived from Leema's Quattro Infinity design first used in the Antila IIS ECO, ensures that the Elements DAC has outstanding technical performance. All inputs, including the USB input, offer full 24 bit/192 kHz capability. The USB input uses asynchronous mode to control a connected computer for almost invisible levels of jitter and to ensure the highest possible quality of digital replay.

The inclusion of an analogue volume control allows the Elements DAC to be used as a very high quality preamplifier. The digital volume control fitted to some DACs actually works by reducing resolution at the same time as attenuating the signal, making them a poor choice for high resolution audio. In addition to the analogue volume control, the Elements DAC features infra-red remote control, a mute button and an on-board headphone amplifier so it can operate perfectly as both a DAC and a high quality pre-amplifier.

Full LIPS® implementation allows for easy system integration with other Leema products and home automation systems.

Bladelius - Best Buy?

Bladelius Embla Standard DAC/Pre
http://www.bladelius.com/products/blade ... embla.html
Preis: 3.000,- USD
Bladelius has released a new stripped-down version of the Embla shown last year at a very stripped-down price: $3,000. What they've taken out is the solid-state hard drives and disc player, leaving those items to the network. In addition to the front panel touchscreen, here is an UPnP server and custom iPad app as well.
Das Teil hat TI/BB Dacs und läuft sogar als ADC.

Wenn das alles stimmt, dann ist das mein Best Buy.
Ich bleibe dran, denn mit den drei Filtern hört sich das nach dem Wadia Algorithmus an.
Und der ist bislang ungeschlagen.....

The Bladelius Embla is marketed as a 'completely silent playback system' much like the Bryston BDP-1, but the difference is that this is a one-box solution that features a built-in DAC and ADC (Analogue-Digital Converter), a normal CD player, a bit-perfect ripper, USB inputs and a preamp as well.

Indeed with the Bladelius Embla, you will save on a few pairs of interconnects and unlike other all-in-one systems, this is aimed at the high-end and is priced accordingly (RM37,000 in Malaysia).

The Swedish-made Bladelius Embla is a large boxy component with simple and clean lines that exemplify the best of Scandinavian design.

Inside, it is far from simple. Just take a look at the number of inputs and outputs on the rear panel. Digital inputs - one AES/EBU, one RCA, one toslink, two USB, one RJ45 and one Bluetooth. Analogue inputs - one pair balanced and two pairs single-ended. Digital outputs - one AES/EBU, one RCA and one Toslink: Analogue outputs: One pair balanced and two pairs single-ended. All these are placed neatly in a row at the bottom of the rear panel.

Essentially what the Embla does is play a CD like a normal CD player and you have the option to rip it into its built-in flash memory and play the ripped file. The ripped file can also be copied to a thumb drive or external hard disk.

A laptop can be connected via one USB input to play music while a thumb drive or external hard disk can be used to play hi-res files from the other USB input.

There is an ethernet input which can be used to connect to a wi-fi router (for an iPad to control the Embla) and to which a Network-Attached Storage (NAS) can be fitted and hi-res files can be streamed from it.

A few days after I picked up the Embla (Full Version) from Eugene Ngoh of Audiomatic in Amcorp Mall, Petaling Jaya, I had to return it because Bladelius had just launched its iPad app (downloadable from Apple store at US$199) and Eugene wanted to download the latest OS (software version 01.07.02 and DAC software version v1.61) which supports the iPad app. The latest OS also supports Mandarin.

The touch screen of the Embla looks very cool.

The Embla has a touch screen which was very sensitive (its sensitivity can be adjusted) while the remote control looked good and was well-made since it was probably carved from a block of aluminium, but its buttons were too tiny.

The buttons on the remote control are too tiny.

The Embla has so many functions that I took quite some time to check them out.

The preamp section

The differences between the Embla Basic and the Embla Full Version are that the latter has a touch screen, a second DAC card which has two more filters, analogue inputs and an ADC feature.

I must say the Bladelius Embla’s preamp section is first-class and easily eclipsed the preamp section of the resident Benchmark DAC1 Pre, which - of course - is much cheaper.

I believe the Embla’s preamp section can take on standalone preamps costing up to RM20,000.

Since I was also reviewing an FM Acoustics FM122 Mk II Phono Linearizer, I spent many hours spinning vinyl on my much-modded Rega Planar 3 with RB250 tonearm and Benz Micro Glider MC cartridge using the preamp section of the Embla.

I was rewarded with a quite organic, full-bodied and smooth sound with excellent soundstaging and tonal colours.

The volume, which is in the analogue domain, can be controlled by the touch screen, the remote control or the iPad.


Playing a CD

There is no tray that slides out; instead there is a narrow slot into which you push the CD - gently. Since it is narrow and has no soft lining, you have to be careful when you push in the CD and take out it out.

Someone had commented that his CD was scratched by the slot, but I pushed a CD in and ejected it several times and noticed no scratch at all. You just have to be careful and gentle.
The CD slot is rather narrow, so you have
to push the CD in gently and carefully.

The Embla also plays data disks. I slipped in a Reference Recording HRx disc containing WAV files and the Embla played it.

You can set the Embla to rip the CD before playing or play the CD without ripping it. I ripped two CDs - Fleetwood Mac Greatest Hits and Patricia Barber Cafe Blue SACD/CD and the time taken varied - the former took 15 minutes and the latter took only five minutes.

After ripping, the number of corrected errors is shown.

Surprisingly, the Fleetwood Mac CD had fewer ‘corrected errors’ - only 690 - compared with the Patricia Barber hybrid SACD/CD which had 94,080.

Used as a CD player, the Embla sounded detailed, rich and smooth.

However, since the Embla sounded so much better when playing low-res and hi-res files from a thumb drive or external hard disk through the USB input, I did not use it as a CD player that often.

Playing from internal flash memory

As expected, the sound was smoother playing the bit-perfect files from internal memory compared with playing directly from the CD. This was not unexpected as in my experience, ripped CD 16/44.1 files streamed from a laptop via USB to an external DAC have always sounded better and smoother than the original CD.

This, I believe, is due to the errors when the laser reads the pits on the CD and the error-correction circuit has to extrapolate on the fly.

The Embla’s internal memory is flash-based and is expandable from 32GB to 2TB.

Streaming from a laptop
When you use a laptop to stream music to the Embla, you have to use the USB input located in the middle of the row of inputs.
I used J River as the music player and the sampling frequency shown on the touch screen was 48KHz. Bladelius has confirmed that 48KHz is the standard sampling rate for this particular USB input.
The sound quality was okay, but since it could not stream at higher sampling rates, I decided to try the other USB input.
Using a thumb drive or external hard disk
The second USB input is located just below the power cord connection. First I plugged in a USB-powered 500GB Western Digital external hard disk. Nothing happened, so I telephoned Eugene Ngoh who told me that I had to use an external hard disk with its own power supply.
Then I plugged in a 4GB thumb drive. Again nothing happened, so I telephoned Eugene again and he told me that the thumb drive had to be in FAT32 format. I googled around and found out that some thumb drives are in the exFAT or the so-called FAT64 format which is not currently compatible with all USB inputs.
I looked around my drawer and found an old Kingston 2GB thumb drive which had some hi-res music files stored in it. I plugged it into the Embla - and it worked.
To stream music this way, you have to turn on the ‘external buffer’ otherwise the sound quality will be adversely affected. With the buffer on, the sound becomes ‘relaxed’, very detailed, smooth and spacious.
The Buffalo 1TB external hard disk which
was plugged into the Embla's USB input.
This mode extracted the best from the Embla - the music sounded fabulous with great clarity and a huge soundstage. I felt it sounded even better than playing from its internal memory.
I spent most of the time listening to the Embla in this mode.
Later, I hooked up a Buffalo 1TB external hard disk with its own power supply and just played all the hi-res files in it - from Linn 24/88.2 Studio Master FLAC files to HDTT 24/192 classical music WAV files.
I had three Reference Recordings HRx 176.4 files and these caused some loud hissing sound and I tried to figure out what was wrong. I deleted those files and downloaded the same titles again from the Internet and again the hissing sound was there.
So I telephoned Koo, Eugene’s business partner, who handed to me an original Reference Recordings’ HRx data disk (Thinking About Bix by Dick Hyman) containing WAV files.
I slipped it into the CD compartment and the 176.4 HRx WAV files played without any hissing sound. Then I copied the files into the laptop and transferred them to the external hard disk and the HRx WAV files were streamed to the USB input and they played without any hissing sound.
So the hissing sound from the downloaded-from-Internet HRx tracks was probably caused by corrupted files.
The Embla plays PCM, WAV, HRx, FLAC, MP3 and OGG with tag information and files are supported up to 32bit 192 kHz via this particular USB input.

Using the filters
The Embla has two separate balanced DAC configurations (2 DACs/channel) to provide two different sonic signatures.
It also has three filters - Filter A has its DAC (Burr-Brown) and filter based on the reference CD player Bladelius Gondul while Filter B uses a different DAC (Wolfson) and Filter C is tuned for an analogue sound (the filter is set to minimum phase type without pre ringing). Resampling is automatically chosen when set at Filter C.
There is also a feature which sets resampling at 44.1, 48, 96 and 192KHz. Resampling can also be turned off.
When using Filter A, the sound - which supposedly has pre-ringing artifacts - is the most exciting and dynamic of the three filters. The dynamics of the leading edges of music were retained and to my ears, this was the best-sounding mode, especially when playing rock songs.
With Filter B, the sound was a bit purer but the leading edges were rounded off and overall the sound lacked some sizzle.
The Filter and Resampling modes.
Filter C was something I used when I didn’t have time to spare to fool around with the resampling feature since the resampling rate was automatically selected for best performance.
I felt that MP3 and ripped CD files sounded best when resampled to 96KHz (with Filter A) while hi-res files such as 24/88.2, 24/96, 24/176.4 and 24/192 sounded best with Filter A and the resampling turned off. I still believe that hi-res files should be played in their native sampling frequencies.

iPad app
To get the iPad app going, you need to connect a wi-fi router to the ethernet input. If the wi-fi router is connected to the Internet, then album art will be shown on the touch screen and the iPad.
If a CD is ripped while the Embla is connected to the Internet, album art will be stored in the internal memory along with the music files.
Album art is shown on both the
Embla's touch screen and the iPad.
Availability of album art depends on the album played - not all album covers will be displayed.
When using the iPad (or even the remote control), it is best not to flood the Embla with too many commands too quickly as the player can get confused.
Since the remote control has such tiny buttons, I found the iPad app to be very useful and after a while I felt a bit lost without it. However, there were some functions that could be controlled only by the remote control or touch screen.

Using the ADC
Since the turntable was hooked up to the Embla, I decided to test the ADC function. The sampling frequency can be set to 96 or 192 and I found the 192 setting to sound better.
With digital out, it is possible to connect the Embla to a recorder so that vinyl can be ripped and stored as digital files.
However, I felt that digitising vinyl playback removed some of the spatial information from the music. Somehow, listening to vinyl through the ADC even with 192KHz sampling was not the same as listening to vinyl directly. Something went missing in the digitising process and I think it affects soundstaging and spaciousness. There seemed to be less space around and between the instruments and singers after digitising.

Other functions
The Embla is also supposed to be able to play files from a NAS connected via ethernet, but I did not try that. According to Bladelius, the ethernet input also accepts up to 32/192.

It is also supposed to be able to play songs via Bluetooth, but I tried to play some MP3 songs from my Nokia handphone without success as the handphone could not locate any Bluetooth device. Apparently the Bluetooth function will only be available with a software update some time in the future.

Finally...

Michael Bladelius, the owner and designer of the company, has come up with an all-in-one high-end component that performs very well. To me the only thing missing is a headphone jack.

To his credit, the Embla is a great-sounding component that covers (almost) all the bases and it certainly deserves all the accolades that it has received.

As a CD player, it sounds very smooth, detailed and rich, but when a thumb drive or hard disk with hi-res files is plugged into the USB input, its performance is elevated to another level and it would not be a misfit among the Weiss, Berkeley and dCS.

Leider waren mehrere Angaben nicht korrekt:
1. Preis: Standard ($4,500), Basic ($6,000) and Classic ($9,000). Der Classic (hat dann auch noch drei Analogeingänge) wird in DE für

SEK.

2. Als DAC kommt keinTI/BB zum Einsatz, sondern ein Cirrus Logic.
Then we have a Burr Brown DIT4192I transmitter chip and finally a 24/192 Cirrus Logic CS5361 A/D converter with 114dB of dynamic range. Because we can record analog signals from radio or turntable to internal memory, this chip is not far from the analog inputs which are handled by Burr-Brown OPA2184s, one per channel. The upsampler and volume control IC too are covered by copper plates. The output circuits are mounted to the side apart from other circuitry. One channel sits on the main PCB, the other on an additional board connected via gold pin. The DAC chip on the top is also covered with a copper plate but not the one on the main PCB. Mike probably decided that shielding through the additional board was sufficient. This chip is the DSD1792, a 24/192 sigma-delta unit capable of converting DSD and PCM signals. I/V conversion is by four BB OPA604 ICs, the ones on the lower PCB run heat sinks. The outputs use two more of these chips. Everywhere we see very good capacitors – Dubilier electrolytics, Sanyos and Wima polypropylene. The clock is thermally compensated and stabilized and also used for the drive, the best solution for digital.

Bel Canto DAC3.5VB MK II

Interessantes Teil. Es kann mit einem "virtual battery supply"-Netzteil betrieben werden. Hat hier schon jemand Erfahrungen mit diesem Pre/DAC sammeln können? Der Preis dürfte (einschließlich des o.g. Netzteils) bei ca. 5000 EUR liegen.

The DAC3.5VB mkII converts your digital media into music providing maximum system performance and control with the most direct connection to your amplifier. The DAC3.5VB delivers the highest dynamic range and lowest output noise from both analog and digital sources revealing the subtle detail in your music.

The Bel Canto Dual-Differential DAC3.5VB mkII Control Center features a class leading 126dB dynamic range with our proprietary low noise digital to analog convertor core. Including five 24/192 digital inputs, high speed ST fiber and a 24/192 ADC analog input, the DAC3.5VB mkII integrates and controls all of your audio sources including an analog input for a phono preamp or Home Theater Bypass. The front panel features a single multifunction control knob that selects inputs and controls volume level. The DAC3.5VB also includes our new 8 character alpha-numeric display and the ability to control balance, absolute phase and to rename and disable unused inputs.

The foundation of the DAC3.5VB mkII is our jitter-eliminating Master Reference Ultra-Clock circuitry that ensures that jitter from any source is reduced below the audible threshold. The 24-bit digital volume control is completely transparent and accurate throughout the volume range. This precision continues with custom Caddock resistors, class-A output circuitry and low noise power supply components. The heavy-gauge all-steel chassis design prevents mechanical resonance from compromising the audio signal quality.

The internal VB supply is designed to be driven from either our LNS1 or VBS1 virtual battery supply and includes a massive 400,000uF of filter capacitance and a sophisticated ultra low noise isolated switching supply for the analog section. All of this technology prevents power line noise from corrupting the delicate audio signals.

Green, low-heat, efficient isolated power supplies and a finely-tuned analog output stage make possible Bel Canto’s eco-friendly compact designs; Bel Canto music products are fine instruments that are musically satisfying, discrete and sleek enough to fit any room.

Preis: 2995 USD
The EXIMUS DP1 is a high-end digital to analog converter up to 192kHz/24Bit, which can also be used as a pure preamplifier and top-quality headphone amplifier.

The DP1 has 6 digital inputs including USB 2.0. Each input supports playback of files up to 192kHz/24Bit (44.1, 48, 88.2, 96, 176.4, 192kHz). For USB this is accomplished with the ultimate USB 2.0 solution from XMOS with its super-quality oscillators (2 separate oscillators for the multiples of 44.1 and 48kHz).

Alex Rasmussen of A-Rex/Neal Feay designed the chassis cosmetics. Alex owns a full-capacity machine shop in Santa Barbara, CA and is famous for his remarkable industrial designs for Ayre, Constellation Audio, Resolution Audio and many others. The basic design concept of the chassis is the leaf. It represents springtime and with it the month of April like our company name. The volume control, engraved details on the top and all the lines are based on this leaf theme.

NuForce DAC-100, 24bit/192kHz DAC, Vor­ver­stär­ker und Class-A Kopfhörerverstärker

Der neue NuForce DAC-100 ver­ei­nigt Digital-Analog-Wander, Vor­ver­stär­ker und Class-A-Kopfhörerverstärker in einem Gerät.

Der sehr hoch­wer­tige Digital-Analog-Wandler kann Signale von bis zu 24bit/192kHz ver­ar­bei­ten, als Ein­gänge ste­hen USB, S/PDIF optisch und S/PDIF koaxial zur Ver­fü­gung. Die Musik­über­tra­gung via USB erfolgt im asyn­chro­nen Modus, die ein­ge­hen­den Signale wer­den mit­tels des sog. Data-Re-Clocking über einen sehr hoch­wer­ti­gen Takt­ge­ber ohne Upsam­pling ver­ar­bei­tet, so dass ein nahezu jit­ter­freies Signal und ein sehr detail­rei­cher, natür­li­cher Klang erreicht wird.

Die kur­zen Signal­wege im Vor­ver­stär­ker ermög­li­chen ein Höchst­maß an Klang­qua­li­tät. Als zusätz­li­che Beson­der­heit ist ein digi­ta­ler 32bit-Lautstärkeregler ver­baut, der eine sehr prä­zise und ver­lust­freie Ein­stel­lung der Laut­stärke garantiert.

Der Class-A Kopf­hö­rer­ver­stär­ker leis­tet 500mW unbd kann selbst anspruchs­vollste Kopf­hö­rer bedie­nen. Der NuFo­prce DAC-100 ist in schwarz und in weiß erhält­lich, die UVP des Her­stel­lers beträgt 1099 Euro inkl. MwSt..
