if you have m9xx, don't buy Topping D70 or DX7s because of XLR output.
m9xx sounds warmer and able to deliver much dynamic and detail especially on bass/mid.
If you need XLR, just get a switch box like JBL M-Patch 2 , it can switch RCA to XLR...
Don't make the same mistake I did....
patrckSo you sold your d70? That's interesting that the dac is better but grace designs has a history in good quality audio
Edit: I just compared my d70 to my sdac and it was beaten easily in resolution. I imagine this dac to be even better
patrckInteresting, I just ordered the DX7 Pro as an 'upgrade' so that I can drive higher impedance headphones such as HD6xx. Will be interesting to compare them side by side
