World Premiere Review!
Wyred 4 Sound DAC-2 DSDse DAC
Great resolution and dynamic range without the old DAC decoding artifacts.
Review By Rick LaFaver


Wyred 4 Sound DAC-2 DSDse DAC  A longstanding battle existed in the era of round shiny discs. Which player could play all of them and do them all quite well. This battle caused an era of "Jack-of-all-trades masters-of-none" until the Oppo BDP-95 came out just in time for digital media to practically take over the audiophile world. Now with digital media there are five times as many types of "round shiny disks" when one considers all of the bit rates, bit depths, and sampling frequencies the iterations are endless... 16, 24, 32, and now 64 and 128 bit DSD files, with sample rates of up to 384 kHz make for infinite possibilities. It takes a very resilient device that is overly engineered and backed by a great software suite to be able to reproduce all of these files into music and do it well.

Wyred 4 Sound was among the first to take up the challenge, and with the DAC-2 DSDse DAC it delivers. The DSDse DAC is capable of bit depths of up to 128 bit (DSD only) with sample rates of up to 384kHz. This is an impressive feat in itself, considering we are only a few years removed from most DACs being capped at 96kHz/24-bit PCM via USB. With the design goals achieved, the true test was putting it through its paces and seeing if the SE DAC could really deliver all of these files with the refinement and ease that one would expect from a high quality DAC with a low enough noise floor to truly appreciate the differences between the different formats.

Putting The DSD SE In Action With Various File Formats
Wyred 4 Sound DAC-2 DSDse DACAfter installing the included firmware and properly configuring Foobar to bitstream the files bit perfect to the DAC as an external audio device, I queued up the most obscure files I could find. Self-recorded 96kHz/24-bit PCM ISOs I had recorded direct from virgin vinyl. Also used DSD 64 and DSD 128 tracks plus all bitrates and sampling frequencies I could find. If it were in front of a real firing squad, the DAC would have been James Bond being fired at by a baddie, ye come away untouched. The DSDse does a great job of decoding all formats after a little tweaking with the different components in Foobar, there wasn’t a single track that flummoxed the SE. Not only did it perform well, but the front readout was always accurate and there wasn’t the usual delay and hiccup in the playback that usually occurs. Read: playback started immediately. This implementation of the ESS reference chip is one of the best I have been able to use. It is very resilient and very user friendly. The only difficult part is configuring your windows based system to just leave the files alone and trust that the Wyred 4 Sound DAC would handle everything. After delving deep for challenging content through my library of music to challenge the DAC, I am confident it decodes almost every format I can think of, and does a good job doing so.


But How Does It Sound?
Wyred 4 Sound DAC-2 DSDse DACAlthough the DAC-2 DSDse is capable of decoding everything, it does manage to sound as if it specialized in almost all of them. This is particularly true with high resolution PCM and 64 bit DSD. All of the formats sounded good and there was certainly differentiation between the formats, but these two sounded by far and away the best. The currently considered high resolution PCM 48kHz/24-bit and above were amazing, with great resolution, dynamic range and low noise floor. All this yet without any of the decoding artifacts that could sometime be heard on older DACs. As good as top quality PCM sounds, the DSD recordings I listened to were even better! Some of the higher resolution DSD (DSD128) didn’t sound quite as clean, but I would attribute this more to the maturity of the file format more so than the capabilities of the DAC. I listened to some high resolution DSD files after being down converted to PCM, yet some of the noise and digititus remained. The DSDse allows you to hear the music without particularly introducing any real sonic signature of its own. It allows a track that normally images well to really shine, and poor recordings sound as poorly as they should. The amazingly high >115dB S/N ratio and >98dB of channel separation, along with a resolving set of speakers, really allows you to differentiate between high quality recordings in the various formats.


Wyred 4 Sound DAC-2 DSDse DACAssigning the Wyred 4 Sound with specific sonic characteristics is difficult, as the best a DAC can do is completely remove itself from the sonic experience. On most tracks the DSDse does just that, completely removes itself from the sonic experience. The soundstage is vast and uncolored and the leading and trailing edges of notes have great attack and sustain. Particularly, cymbals on orchestral music. Horns and strings in small ensemble are a tremendous step up from the Eastern Electric MiniMax that is my everyday DAC. Comparing the DSDse to something in the über DAC category, like the Empirical Audio Overdrive, the DSDse is slightly lacking in the analog character that the Overdrive squeezes out of recordings. Then again it should at nearly three times the price,. Even so, the Wyred 4 Sound supports a far greater breadth of formats and is very close in channel separation and S/N. In its price range, the DAC-2 DSDse gives up very little if anything to its pricier competitors in sonic performance.

Pros: Bulletproof across all formats I could find. Great remote with a comprehensive menu, multiple inputs and outputs with impedance matching using gain controls plus it is easily upgradeable should Wyred 4 Sound come out with any further feature sets. You also get a very low noise floor and five year warranty.

Cons: For me it is styling, plus for newbies it may take a certain degree of technical knowledge to enable DSD64 and DSD128 playback.
