As an amp suggestion, I bought a C-J LP66S and it's awesome. So much depth and realism to music. As a DAC suggestion, the CIAudio VDA2 & VAC1 have also been great. I bought the amp as a dealer demo & the DAC used here on A-gon. Of course they sound great here at my place, but they could work for you. The rest of your system looks great. G'day!
