A few I’ve been considering that seem to hit well above their retail price…
Okto dac 8 - interesting approach in optimizing a Sabre chip, also unique in their output stage
Gustard R or A26
Ladder Schuman
Have to say that anyone putting down any/all Topping DAC offerings is sadly mistaken. Although, I do agree the D90 is rather not right in the midrange. But currently using a D70s that sounds pretty damned wonderful. Really nice output stage on that one. It compares favorably against a Denafrips Pontus II. Has a surprisingly similar presentation to that of ladder dacs in general. Would say the Pontus still wins it out, but not by a very wide margin (heard each in the same system).
