I say to you you can’t go wrong, compared to others mentioned so far
It’s an easy thing to say when you are spending someone else’s money.
Personally, I wouldn’t be buying anything at that price level without an audition, and I certainly wouldn’t be buying it on George’s advice.
The MSB gets mixed reports - some very positive, and others suggesting it sounds rolled off, and lacking dynamics. I’ve never heard an MSB dac but the two R2R dacs I have owned - a Metrum Pavane and Holo Spring - have both suffered from high frequency roll off and a lack of dynamic impact. At its price, I would expect the MSB to be much better, but I wouldn’t take the gamble that it was without hearing it myself.
The only DAC on the list I have heard is the Lumin X1, and I own one. I prefer it to the Chord DAVE/Blu 2 which preceded it and it is vastly better than the two R2R dacs I mentioned. The Bartok is also getting very positive reviews and if you have the chance to hear one you should definitely do so.
