Main Review

Denafrips Terminator //// Schiit Yggdrasil

This comparison is both an evaluation of each DAC and a comparison between them.

The Schiit Yggdrasil is the A version with the Gen5 USB board upgrade. I plan to send it in for the analog B board upgrade, pending wide owner feedback on the benefits of the upgrade.

The Denafrips Terminator is current stock.

Draft Version: 3/5/2018
Evaluation Concluded 2/25/2018

------------------------------------------------------------------------------------------------------------------------

This is a story of contrasts, significant and relevant to me.  A story of something new and unknown that upends and unseats something familiar and remarkably good in it's own right.

 I remember John Darko's review of the HiFiMan HE-1000 headphones that was all of one sentence:

"The HE-1000 headphones are to music what the Oculus Rift is to computer gaming."

Sometimes the best choice is to be direct. So I will.



Similar minimalism could wishfully avoid writing. A set of two photographs in one frame, the picture is worth a thousand words approach: The Yggdrasil sitting in a corner of the room unused and the Terminator in the main system on the top shelf. One way of saying it. And true.

The Yggdrasil is a very good DAC. When heard in relation to the Terminator it is clearly the lesser DAC.  Being a fan of the Yggdrasil and having lived with it for 2 plus years I had a natural bias to want it to shine and be close in performance, perhaps even overachieve. It wasn't and didn't. This became apparent track after track, and without exception. I kept telling myself that there would be an area or areas that I would prefer it over the Terminator but there were none. And for, me that is the most surprising and revelatory outcome. I expected the Terminator to do well but with closer differences and separation. The differences were not close and the Terminator didn't just do well, it excelled.

This was not a case of new component excitement. I have lived with the Terminator in my system since early November and have become as intimately familiar with it as I have with the Yggdrasil. This was also not a case of listening in a vacuum or my own bubble.  I'm especially careful and deliberate about not falling into that trap. My audio friends know the degree to which I reach out to them to run findings, issues and general aspects of our hobby by them, positive and negative.

I was especially concerned because of how wide the gap between the two components is for me. I went the extra step to have an audio friend listen to both the Terminator and the Yggdrasil in his system and then in my system. His impressions and findings are (generally speaking) similar to mine. He had actually been considering a Yggdrasil seriously but what he heard led him to choose the Terminator, very recently in fact. To summarize his findings, in his words: "The Terminator plays in another league."

I'll highlight two findings with respect to the Yggdrasil. One very surprising aspect was a light haziness or grayness that I had not picked up nor realized prior to having the Terminator in system. Like how small amounts of particulate pollution affect clarity in the sky. Even more surprising was how my system with the Yggy in it, sounded like recorded music, fleshed out only due to the contrast and comparison.

The Yggdrasil is a DAC the Schiit team are rightfully proud of as are numerous owners, myself included. Their flagship DAC has had incredible success in sales numbers and sustains a happy cadre of owners. I personally like and respect Schiit's business model and I believe Jason and Mike have done more for the hobby by bringing so many into it than most other manufacturers, many combined, in recent years. A tip of the hat to their team for manufacturing a wonderful component that has given me over two years of pleasure. When I get around to setting my office system up it will continue to be a key piece in that system. To up the ante with a call to arms, I'd love to see another all out DAC assault by Mike and Jason and I will gladly commit to one.



On to the Terminator.

When I know that 'I know' moments aren't common, yet when they occur they are a proverbial 'wire with gain' shot to the brain and an effective and unfailing guide to component choice.

Additionally: What do I keep reaching for and what sits unused? What just feels right when first introduced into my system or when re-inserted once fully broken in?  Do my notes with single word descriptors or short phrases repeat track after track and become thematic? Does the component have 'a presence' in my system and does it deliver 'a heightened sense' of being in the zone musically and emotionally? Does it elicit a feeling of satisfaction and accomplishment?

The Terminator checks all of these boxes. It's performance and place in my system was undeniable.

Music is presented as Fuller and Richer, with Denser Body and Weight yet Transients remain Fast and Leading Edges Sharp and superbly Defined and the Trails and Decays decadent and lengthy. There is a tremendous sense of Presence and Faithfulness in Timing. Harmonics are Expertly Expressed. These areas, in how and to the degree they are rendered with the Terminator, is extraordinary.

Imaging is rock solid (really quite marvelous). The background is blacker with a lower noise floor (superb). Both are remarkably better than the Yggdrasil. Soundstage is wide and deep and 3 dimensional with the listener in the audience pushed back a few rows or conversely the stage moved back somewhat (which I prefer to a more forward presentation). Soundstage is one area where I found the Yggdrasil and Terminator to be relative equals, with the Yggdrasil being more forward.

It's abilities with Detail, Layering, Separation and Definition, are all the more astonishing given the richness and density extracted from the music and portrayed, both maintained even at the micro-detail / micro-dynamic levels of musical information. First instincts suggested a lack of resolution and transparency...but Resolution and Transparency are outstanding. I find (make that found) the Yggdrasil to be an overachiever in this area. With the Terminator it becomes obvious that the Yggdrasil does well at this with a cost exacted elsewhere. In fact, the Terminator makes it clear as daylight that it is more resolving and transparent than the Yggdrasil while not calling overt attention to this. To me this is astounding because while much more of the detail and musical information is present it is not spotlighted and I found myself slipping into the embrace of the richness and beauty of the musical whole...and this was while critically listening!

It pulses and shimmers and floats with Energy and Vibrancy and Resonance while delivering IMPRESSIVE IMPACT and DYNAMICS. Felt Tension and Emotion are the best I have experienced in any of my systems and most that I have auditioned, save mega dollar statement ones. My system is now more Connective and Engaging than ever. It makes music Alive (vs. just Live) and does a fantastic job at creating the illusion of Performance Space and transporting me THERE! Yes, as in, I AM THERE.

There is a Rightness and Truthfulness delivered with nuance, delicacy, sweetness, sadness, anger, beauty, rawness, etc. etc. all musically painted with resolute naturalness.

Simply put, it gets music and musical performance RIGHT. And in doing so, is so so very satisfying.



Closing Words.

When conducting these evaluations it is easy to focus on the component and lose sight of the whole. I take a system level view and hear and interpret these findings as system related. In other words, the rest of the system allows the Terminator to showcase itself and it's potential. Without this system, my system, the findings may well be different. Without the guy (me) that is busy typing the letters of the English alphabet on this digital page and his unique to him musical experience and journey, the findings may well be different.

I would like to recognize and congratulate Mr. Zhao of DENAFRIPS for his STUNNING electronic creation. Bravo! Please accept my deep bow of appreciation for the joy your Terminator DAC has brought to my home and my enjoyment of music.

I also want to tip my hat to all of the manufacturers and their teams for designing and building the components and cabling and peripherals of my system, all of which allow me to experience the expression of human creativity and beauty through the musical art form.


--------------------------------------------------------------------------------------------------------------------------


Next Steps.

For me, there is nothing endgame about this hobby. I believe 'endgame' is one's personal choice to end the game for themselves. It is not bound by the component.

My journey with one DAC has come to an end and is just starting with another. Will there be other partners in the future, I sure as heck hope so. Stay tuned.

Method, System, Room, Music

Denafrips Terminator //// Schiit Yggdrasil

This review is an evaluation of each DAC and a comparison between them.

The Schiit Yggdrasil is the A version with the Gen5 USB board upgrade. I plan to send it in for the analog B board upgrade, pending more owner feedback on the benefits of this upgrade.

The Denafrips Terminator is current stock.

Draft Version: 3/5/2018
Evaluation Concluded 2/25/2018


METHOD

My methodology IS NOT bench rigorous, nor was/is it meant to be.

This is a subjective comparison and evaluation.

Input / Output:  Digital: USB In. Analog: XLR Out.

I believe the process was Fair to both components and was what I could Reasonably Achieve (for example, SAME position on shelf, footers, isolation platform, cabling, tracks, etc.).

I am the owner of both DACs and have no affiliation with Denafrips or Schiit or their agents.

Items of note are listed below.

- Both DACs were continuously energized except for an approximate one minute period when I switched between DACs.  USB and IC cable length restrictions, and not having an equivalent extra PC, necessitated having to swap each DAC out. * (See Below)

- Volume differences were addressed using an SPL App at the listening position at the same height as my ears.  Average SPL over the track length was generally the same i.e. 0dB / +1dB difference with a max difference of +1dB favoring the Yggy. Peak SPL was mostly 0dB in difference with the exceptions being +1dB, again favoring the Yggy. I had to adjust volume on the Pass XP-20 by an additional +2 clicks to +4 clicks for the Yggy to even out volume levels. The Pass XP-20 was also set at equal L/R channel Volume/Gain, throughout. ** (See Below)

Note: The SPL APP was run through the full duration of EVERY single track listened to, to make sure volume levels were as close as possible. Due to variances between tracks, I conducted the test sequence only after equal volume levels were achieved.

- Listening (generally) averaged in the low 70dBs across the length of most tracks with peaks of 87dB - 90dB  Minimum volume was trickier to establish due to inconsistency in music and meter start timings. Low to mid 40dBs is an approximation. Ambient 'noise' in the room registered in the mid 30s to low 40s.

Note: I devoted a lot of time to volume issues because of the feedback from Audiogon Members on the Thread 'Best Practices when Conducting a DAC Comparison.' Thank You to those Members.

- The Synergistic Research Atmosphere Level 4s allow for a Red or Blue Tuning Module. I used the Blue Tuning Module for both DACs. This favored the Yggy as it's sound quality and performance were markedly better via the Blue Module. I find the Terminator to do well with both tuning modules; I did not try any Blue/Red combinations.

- The Synergistic Research ICs were ground to a wall outlet via their base grounding cable/plug.

- The Synergistic Research Tranquility Base UEF were ground to a Shunyata Venom PS8 Power Distribution Strip (wall outlets are best but none were free).

- I had previously conducted a six USB cable shootout and chose the Stealth USB as my top choice. Most of the shootout was conducted before I had the Terminator DAC in system; with the remainder being conducted before it was fully broken in. In other words, my USB cable choice was made based on optimal sound performance with the Yggy in the chain.

- My more recent IC cable comparison was conducted with the fully broken in Terminator in the component chain as the primary DAC, but was also checked and confirmed with the Yggy in the chain. This evaluation resulted in my choosing the Synergistic Research Atmosphere Level 4 XLR ICs over my Cardas Clear Reflection XLR ICs and the loaner Audience Au24 SX XLR ICs.

- All components are factory stock with no modifications. I am also using the Pass supplied DIN-25 umbilical to power the XP-20 from it's power supply.

- All components were fully broken in.

*To make sure the Yggy was not disadvantaged by powering it off for under a minute at a time, I also ran it overnight with full signal through to the speakers. After over nine hours of run time, there were no differences in outcomes (and my findings) after running a few tracks and re-comparing to the Terminator, which was energized but did not have signal running through it over the same nine hour period.

** The SPL App was used as a proxy and therefore is an approximation vs using a fully calibrated SPL Meter or measuring at the speaker binding posts; my goal being approximate equivalency.

MUSIC SELECTION and ADDITIONAL METHODOLOGY


All tracks were listened to in their entirety (except for two tracks -- length noted in parentheses) and in the order listed (See Below).

Sequence of Listening (for each track) by DAC: Denafrips > Schiit > Schiit > Denafrips.

All tracks played were adjusted for volume to be equal for each DAC. I monitored volume level, made gain adjustments to ensure volume equality and continuously monitored volume levels in the background to confirm this.

I was sometimes interrupted -- and when I was, I restarted the process for the track.

Each track was listened to four times, once volume equality was established, for the comparison.

Due to the volume adjustment process and interruptions, some of the tracks were played up to eight times, six times being the baseline.

This critical portion of the evaluation took over 14 hours of active listening / setup time / note taking over a three day period.

The music below is a selection encompassing strings, percussion, Acoustic, World, Fusion, female voice, Jazz, Electronic, spoken word, massed choral, Religious, New Orleans Rock/Funk, male voice, same artist when young and old, etc. It isn't comprehensive but I believe it is varied enough and allowed each DAC to strut it's stuff.

I am intimately familiar with all tracks with the exception of 'Right Place, Wrong Time' and 'Lazarus Man'.

All Files are Tidal FLAC 44.1kHz 16bit 2Ch. No oversampling, additional filters, or DSP applied.
