Mojo Audio Mystique EVO


Mojo Audio updated their website yesterday with details on the next generation of the Mojo Mystique DAC, the Mystique EVO.

Unlike the V3, the EVO has upgrade options for component, isolation and shielding upgrades - at purchase or to be upgraded later.   The website states there are plans to release new boards for ethernet/roon, and other dac chips like the PCM63.

I pre-ordered an EVO in late February with a few upgrades.  I'm expected to receive it in 1-2 weeks, and I'll post my impressions after some time with it.  I currently have the Mystique V3 and I find it fantastic.  Really looking forward to hearing Ben's next iteration.

Hi Everyone.

Benjamin here: owner of Mojo Audio and designer of the Mystique series of DACs.

I wanted to clear up a few things and respond to some of the questions that were asked.

First of all, the difference between our Mystique v1, v2, v3, and EVO:
The v1 and v2 use the same chassis and very similar ciruits. The big difference is the v1 had a direct-coupled output stage from the 18-bit AD1865 DAC chip’s voltage output with no external parts and the v2 uses the current output of the AD1865 with a discrete output stage that has two op amp stages per channel. The same output stage circuit used in our v3 and EVO.

In later versions of the v2, such as the v2+, v2SE, and our current v2X, the output stage uses the same discrete Sparkos op amps, Vishay TX2575 "Nude" resistors, and foil and film caps as our v3. Quite an improvement.

Our new v2X uses an XMOS USB input module that not only makes it more compatible with more operating systems, it also improves performance quite a bit as well.

Our v3 and EVO use nearly identical circuits to the v2 but with the 20-bit AD1862, better signal path modules and parts, better shielding, better grounding, better mechanical resonance, and 5X LC choke-input power supplies vs the 2X capacitive input power supplies that are used in our v1 and v2 DACs.

Our EVO is basically the same circuit as our v3, but with upgrades to the USB input, S/PDIF input, analog output, shielding, grounding, and mechanical resonance. And where as the v3 has two circuit boards (PSU and signal) with one .25" thick ferrous shielding barrier between them the EVO has three circuit boards (PSU, digital, and analog) and has a second .25" thick ferrous shielding barrier between the digital and analog boards.

Sound quality wise the entry-level EVO Basic sounds better in all ways than our v3.

The EVO is also divided into three versions: Basic, B4B, and Pro. B4B stands for "Bang for the Buck" and is our recommendation to most of our customers. With each upgraded version there are "freebies" in terms of upgrade options, so it pays to buy the entry-level B4B over a Basic with all the upgrades, and it pays to buy the entry-level Pro vs a B4B with all the upgrades.

And of course the EVO is engineered to be upgraded at any time in the future with better digital and analog signal path part options, advanced shielding material options, advanced anti-resonance options, better wiring and connector options, better AC filter options, and significantly better power supply options.

We’re already planning entirely new digital, analog, and PSU boards for the future with significant performance upgrades. And all of those boards will fit in our current EVO chassis.

The big performance upgrade would be to upgrade the chokes in the analog power supplies to the Lundahl or Lundahl amorphous core. That is where the "magic" comes from. It would be nice if some of you guys who upgraded your v3 or EVO with the Lundahl chokes could chime in and describe what you are hearing.

Of course both the analog signal path upgrade and Lundahl chokes in the analog section are included in the B4B, along with a few freebee upgrades.

We often get v2s traded in that will show up on the Specials page of our website. We rarely get any v3s traded in. When we get a v3 traded in it is usually pre-sold before we even post it on our Special’s page.

When we get trade ins we bench test them and adjust the trim pots for DC offset and MSB at the zero crossing (DAC chip linearity). Few companies who use the same DAC chips and op amps use these fine tune circuits even though they are on the data sheets of all the R-2R DAC chips and op amps we use. Something to think about.

When we resell used gear it comes with our standard 45-day no-risk audition, 90-day full-value upgrade, infinite trade in options, and a 2-year factory warranty. Our new gear comes with all the same return and upgrade options plus a 5-year warranty.
We usually resell our trade ins for what we pay our custom for them...sort of a discount to our loyal customers. We’ve been offering customers $3,500-$4,500 trade in on v3 DACs depending on version and condition. At $3,500-$4,500 we have a long waiting list to buy a used v3 from us.

So if anyone has a v3 DAC in good condition they want to sell for $2,600 no need to spend $$$ on a listing...I’ll be happy to buy it from you, recondition it, and resell it for $3,500 :^)

The most important thing to remember is the DAC can only give you what you feed it from your digital source. We get customers all the time who have a modest transport or server/streamer and want to buy one of the more expensive versions of our EVO: big waste of $$$. You want to use a digital source that is proportional to your DAC or all your DAC is going to reveal are the flaws in your digital source.

Remember when you could buy a CDP or a transport and DAC and the transports cost roughly the same price as the matching DAC? So we don’t suggest buying anything more expensive than our EVO Basic unless if you have a transport or server that costs over $5K. We would strongly recommend upgrading your digital source first.

And our advanced shielding and anti-resonance options will make very little improvement unless your entire system is of a high enough performance and is using similar shielding and anti-resonant products. So rather than buying a set of Stillpoints Ultra II feet for your EVO we might suggest you spend a similar amount of $$$ to buy Stillpoints Ultra Minis for your entire system if you don’t already have something equivalent.

BTW, we are about to run a few specials with freebees thrown in on our EVO between now and the first of the year. If you want to know about those specials sign up for our e-newsletter. They won’t be advertised anywhere else.

FYI, on January 1st we’re planning on raising the price of our EVO by $500 to compensate for rising parts costs. So it would really pay to purchase one before December 31st.

I hope you all found this helpful.

Feel free to call me if you have any more questions.
Actually ground loops occur when one or more components have a different ground potential.

Then the grounds seek to equalize themselves between the components through the path of least resistance, which is most often your low-impedance analog interconnects.

If all the components were at the same ground potential it wouldn’t matter if they were star grounded, daisy chained, or grounds floating, relative to each other.

The ground lift isolates AC/chassis/Earth grounds from the sensitive DC ground in the EVOs circuit boards, and from the signal that runs through the connectors to the interconnects.

And the grounding post provides the option to create a path of lower resistance between components than the AC safety ground in your power cables or your interconnects.

For advanced system grounding I recommend using the same 24AWG OCC UniCrystal silver wire we use in our digital and analog signal path upgrades. That would create the lowest impedance ground you could get. Ideally you would do this with all of your components and then star ground all of the grounding posts together at the AC safety ground at one of your wall receptacles.

I recommend connecting to the screw that holds the face plate on that receptacle and replacing the screw with a pure copper screw.

This will create a path of least resistance between all the AC grounds in your system and not only eliminate ground loops, but also actually lower the noise floor in your entire system.

All the best custom systems I’ve heard...ones owned by the most advanced DIYers I know...ones you can’t buy for love or $$$...use a dedicated OCC UniCrystal silver star ground between components.

Then you may be asking "what about the resistance of that brass grounding post on the EVO...it make no sense to use silver wire with that in the ground path" and you would be correct.

I’ve been looking for a low impedance grounding post for an EVO grounding upgrade option and I can’t find a copper one let alone a silver one.

I’m actually considering using a Furutech low-mass RCA plug in place of the brass ground post for customers who want to do advanced system grounding.

We already use silver plated wire in a low-impedance daisy chain between our AC/chassis/Earth ground star ground point located near the grounding post in the EVO and the shielding grounds on the balanced connectors in the EVO, and the shielding barriers between the circuit boards in the EVO.
And when you get our copper clad shielding upgrade both of the .25" thick ferrous shielding barriers are laminated with pure copper foil so that any EMI or RFI that contact the shielding barriers is dumped through the low-impedance copper foil, to the silver plated daisy chain wire, to the the grounding star point and grounding post.

As part of our advanced grounding upgrade not only will you get a low-impedance grounding post/connector, the silver plated wire in the daisy chain and the wire going from the ground star to the grounding post/connector will be upgraded to the same OCC UniCrystal silver wire I’m recommending to use between your components in your system star ground.

At Mojo Audio we take grounding and shielding very seriously :^P
Should I change our tag line to "a bit closer to live acoustic music?"

In any event, the big jump in performance in our 2021 versions over our 2020 versions is the Staccato class A op amps over the Sparkos SS2590 Pro op amps.

If you purchased a 2020 version with the Sparkos op amps we can upgrade you to the new Staccato op amps for only $500.

After all, you did buy an EVO :^)
A new review is out in Head-Fi:

Just in case you’re wondering Taylor02, we’ve replace quite a few Bricasti DACs.

IMO there is no comparison between Delta-Sigma and R-2R.
The question is: would you like the the flavor of sugar added to all your food? Well, Delta-Sigma is digital sugar.

Delta-Sigma is based on error correcting algorithms that always assume there is an error. And those algorithms can’t tell the difference between a bit read error and emotional content in the music. To my ear all Delta-Sigma DACs sound pasteurized, homogenized, and overly refined.
Nothing wrong with that...some people love that sound...that’s why Baskin Robbins has 31 flavors, right?
On the other hand, R-2R will give you whatever is on the recording, good, bad, or otherwise.
Your best recordings will sound better than ever but your bad recordings will sound worse than ever. That’s the price you pay for accurate digital reproduction.

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.
I’ve owned the whose who in CD transports: CEC, Teac VRDS, even an old all metal CDM-1 in a 50 pound Sony deck.

Not one of those sounded even close to the first prototype MacMini music server I built back in 2009 with a linear power supply I made from spare parts laying around my shop.

That’s why I got into computer audio. None of those CD transports held a candle to even the most basic of computer audio.

Earlier this past year I auditioned a McIntosh MCT500: a $5K, very heavy, dual laser, metal disk tray, advanced clocking, CD transport with a USB port.

It was no comparison to my computer audio system. I couldn’t listen to that MCT500 for very long before it fatigued me.

So don’t get me wrong: all CD transports are not better than computer audio. So far the only one I’ve found is the Jay’s transport which sells for about HALF the price of the McIntosh.

There are comparisons between the Jay’s and the CEC and the PWT online. Most people pick the Jay’s transport hands down and find those other transports sound softer, slower, and off time and tune.

Apparently most of the hard core CD spinners these days are going for the top loaders, like the Jay’s, Denefrips, and Pro-Ject.

The first review was just posted for the new Mystique X SE DAC in Audiophilia.

The reviewer used to own a Mystique EVO Pro as his reference DAC but he was to taken by the new Mystique X SE he sold his EVO Pro and bought the demo unit.

Needless to say he awarded the X SE Star Component..

More reviews and awards should be posting over the next few months :^)
