Marantz SA-10 replaced my Esoteric K-01. Never looked back. SA-10 is that good sonically, well worth the money. I use XLR outs. settings, Dither 1, Noiseshaping 3-1, headphone amp off, Gain set to low (does make a difference for some reason, mid is OK, but low is more details). Sound s best ofter being on and in use for a few hours.
