The Audio Aero CAP MKII or the Prima. Or a good tube DAC like the Cal, Kora, VAC, Audio Logic etc.
The Rresolution Opus is not an anolog sounding CDP, but is a great CDP especially for the price. Excellent dynamics. It has to be used with a good power cord like the Shunyata Black Mamba to smooth it out some, it was not harsh or hard sounding but the Mamba made the CDP very smooth and relaxed sounding. It was clearly better that the Accuphase DP-77 SACD/CD player I auditioned with it, the 77 sounded boring and not as dynamic too relaxed and laid back sounding. The Wadia 861 basic bettered both of them but it is more $$$$.
Happy Listening.
