Mojo Audio Mystique EVO

I received my Mojo EVO 2021 B4B about 2 weeks ago and thought I would share some initial thoughts (actually I posted some of the below in another thread, but thought I would re-post some of it here since couple of posters on this thread have asked for EVO owners’ impressions of the DAC).

The EVO 2021 has been a wonderful DAC and the first component change that has totally transformed my system. And it continues to amaze me as I continue to "burn it in". When I added the First Watt Sit-3 into my audio set up, I was happy you could get some of that SET magic/tone from a solid state amp, and then when I introduced the Shindo Masseto preamp into the setup, I got more of that 3D dimensional body and meat on the bones in the music. When I added the EVO into the setup, I (finally) started to enjoy and listen and move to the music, and stopped thinking about and analyzing the sound. With prior DACs in my system (Borderpatrol SE-i, TotalDAC D1-core), I was always analyzing soundstage width/depth, instrument separation, tonality etc. Although these previous DAC’s had moments of "pop" and "excitement", but in the back of mind, those moments always felt exaggerated. To be clear, I am not trying to disparage these other DACs, they are very good DACs at their price points. And given the subjectiveness of audio perception, these "exaggerations" could be another person’s musical bliss. Pick your own poison as they say....

One of the pieces of music that I use as a litmus test is a Chesky recording of Earl Wild (pianist) playing with a full orchestra. Supposedly a very good recording, but it was probably the piece that I skipped past the most when i played that album. The piano tonality was off and just sounded flat, and overall it was like hearing the piano "versus" the orchestra. With the EVO, the piano came alive, and I could finally hear and enjoy Earl Wild’s masterful and nuanced articulation, and, Earl Wild and the orchestra "playing together" and "having a high energy conversation". Quite frankly, I continued to play that piece (even though i didn’t enjoy it that much) each time I introduce a new component into my system because, subconsciously, I guess I was hoping to see which component change would stop me in my tracks to have a second listen. Every CD I have put on since the EVO 2021 arrived, the immediate reaction has not been "wow, I am hearing this new detail or that new detail" (though this is true), but I am just smiling and enjoying the music immensely. The recorded trumpet has always been a tough instrument for me to appreciate because it sounded harsh and lacked richness, but all that changed with the EVO. I actually started to like listening to the trumpet, and I am developing a new found appreciation for Miles Davis.

Hope this was helpful to some. Enjoy the music!

I just wanted to let you all know that my current reference digital source is a modified Jay’s Audio CD transport.

The time, tune, and harmonic coherency is like nothing I’ve ever heard. And I’ve owned some pretty exotic CD transports.

Don’t ask me to explain why, but the best computer audio won’t hold a candle to a proper CD transport. Even those new JCAT XE OCXO clocked USB cards, which has the same type of OCXO clock as the Jay’s CD transport, is not even close.

When I played this for some local audiophiles all their jaws dropped. The sound was so much better than any digital music they ever heard no one ever asked to go back to computer audio for a comparison.

I now consider the best computer audio as background music. The timing and tune are totally messed up. Streaming is worse, but even music played from your music library on an internal SSD is off time and tune.

Seriously. Once you hear it you can’t unhear it. The sound those of you who are real music lovers have been waiting for.

I removed all computers from my main system. If I’m going to warm up my tube amp, I’m going to change CDs from now on.

Because a CD transport is my current reference digital source, the new Mystique X is getting some pretty serious S/PDIF upgrades. I’m even putting a power cut off switch for the USB input which will remove all clocking from inside the DAC chassis and lower the noise floor even further.

For those of you with one of our 2019-2021 EVOs you will be able to get this S/PDIF upgrade by the spring of 2022. We’re also going to offer a PCM63 DAC chip upgrade.

Interesting. I purchased the very good PS Audio PWT transport two weeks ago because I have been hearing folks say what Benjamin just posted. Ben shared this with me recently. So I have a very nice Hijiri Nogami power cord on the transport and the top of the line Hijiri Million Dollar digital cable. I have been comparing the sound to my Innuos Zenith 3 server. I had to find out for myself if CD spinning is still that far ahead.

The answer is not universal or easy. It depends and that is now clear to me. My Innuos Zenith is fed by a Network Acoustics ENO filter, two ENO ethernet cables, an English Electric Switch 8 powered by a top notch LPS and a modem/router powered my a top notch LPS. I have a Tchernov Reference USB cable between the Mojo Evo and Zenith.

I have been conducting listening tests carefully listening for differences and preferences. Here is my conclusion based on my system as outlined above.
- CD spinning sounds very, very similar to CDs ripped and played off the Zenith. Very close. I would give a slight edge in dimension to the CD spinner. Very slight.
- Streaming Qobuz from Roon did not sound as good as the CD spinner. It depended on the Qobuz file quality however. Non - HD Qobuz files sounded the worst. HD Qobuz sounded much better, but still about 85% as good as the CD spinner. It sounded flat compared to CD spinning.
- Using the new Innuos Sense instead of Roon makes things much closer to CD spinning. Roon does not sound as good as the new Sense software from Innuos. Frankly, Sense is much better sounding at the date of this posting. So streaming HD Qobuz files through Innuos Sense is damn close to the CD spinner. Within 5%.

Innuos Sense is coming out with an update next week that is said to sound some 10% better according to beta testers. This will put HD Qobuz files and CD rips on par with CD spinning in my rig. What’s important to remember here is everything matters when it comes to streaming and playing files off a server. Everything matters! The music playback software used is also critical. Roon is no match to Sense sonically as of today. However, Roon continues to improve their sound quality as does Sense. This space is moving fast folks with sound quality improvements coming monthly! Network Acoustics has some new ethernet filters and switches coming that will improve streaming sound quality even more.

No easy or general answer to the question of does CD spinning or streaming/server sound better. Cannot make any broad brush conclusions as it just depends. Too many options, products and variables are at play. In addition, the streaming/server improvements are coming at a very fast rate. Innuos Sense is just one example. Going from Roon to Sense has been a sonic revelation for many of us. Both continue to improve sound quality and that is great news for sure.

Depending on how your system’s digital front end is set up CD spinning may sound much better than a server or it may not. The only way to know is to compare for yourself in your own system. Just FAR too many variables at play for the one simple answer.

For those of you with one of our 2019-2021 EVOs you will be able to get this S/PDIF upgrade by the spring of 2022. We’re also going to offer a PCM63 DAC chip upgrade.

Hey Benjamin, if you want to hit it out of the park, make those upgrades user-installable!
