Mytek Liberty Vs. S.M.S.L VMV D1 DAC


I am after a new Dac for my headphone amp.  Its a computer set up - i.e. USB input, with Tidal and/or Audirvana+.
For my amps I have the THX AAA 789 and Musical Fidelity X-Can V8 tube amp.
Headphones are - Grado GS1000e, Beyerdynamics DT 990 Pro, Sennheiser HD 580 & HD 600, Lenco K106 and  Mitchell & Johnson MJ2. 
My current dac is the Schiit Modi Multibit, and I feel that it right now is the weakest link.

With about  $1K budget, I have more or less narrowed down my choices to one of these two dacs:

Mytek Liberty
S.M.S.L VMV D1 DAC

I have read great things about both and not sure how to decide.

Any opinions? Has anyone compared between the two?

D1 is hands down better (i.e. more transparent), unless you want MQA. I fail to see any benefit MQA brings over PCM (and doesn’t allow digital volume control, hinders DSP integrarion, etc.) so I personally wouldn’t let it influence by gear selection. 
 
I mean, just look at the graphs on Stereophile, no filter selection, so all PCM is routed through the MQA filter, giving us aliasing, and terrible IMD in the treble. Granted, with real-world use it may be of no concern, but unless you want MQA, I see no point in buying a worse performing product.
