Aurender for sure. I have an Aurender W20SE -> Audio Research Reference CD9 DAC -> Audio Research Reference 6SE preamp —> Audio Research 160m mono blocks.
i can’t recommend this enough. Definitely N20 would be my choice if I did not have their flagship. The ARC DAC (go for the REF 9) is an unbelievable, detailed, musical and natural sounding. I had a $22K Berkeley Alpha Reference in my system for a couple weeks… I was prepared to cough up the extra $5K, but the ARC was ever so slightly more natural a musical.
Anyway, my Aurender has basically the same sound as my great analog rig. Send me a PM if you want talk details. My systems are shown under my UserID.
