I am checking out these DAC's for my system

@mitch2 

Thanks Mitch.  The USB board that Mojo uses, the attention to power supplies and the focus on reducing both EMF and external vibration have created a top notch product.  I'm really happy with my Mystique X and hopefully it will serve me for many years to come.

I run the optical connection out of my TV to my two channel stereo because the only other option is the headphone jack. In the past I've used the headphone to RCA connector  which works but it has the potential of over-driving the preamp and causing damage.  I haven't  a clue about converters or how that would even work on a USB input.  you might be able to run the converter and the audio USB output through a USB hub but since I already have the second DAC  I really don't care to try.

I was told by Vlad the major difference between IV & V was

"Completely different tube stage and tube power supply."

But both still have transformer output (no capacitors... the III still uses capacitor output)

Look at the best Denafrips DAC you can afford. Anything Pontus 15th and above is brilliant. The 15th series are virtually the same as the next level up DAC. Most musical and fun DACs to my ears

Pontus 15th same as Venus II 12th

 Venus 15th same as Terminator II 12th

Terminator 15th same as Terminator Plus

They also are releasing the Terminator Plus 15th, and I have no clue what that is

@brbrock , 

You can always return the piece if you don’t like it. Vlad is very easy to work with.

@danager You mentioned the the USB boards on the Mojo DAC’s are exceptional. You are not the first one to mention this. What makes the boards exceptional?  The boards look nice but that is about all I know.
