Sorry, I cannot offer any insight, but I would like to ask you something. Any idea what the PD owner is replacing the unit with?
I can only add that I was about to go analog only and sell off my thousands of cds and then I bought the playback designs and now listen to digital and enjoy it immensely.
It has a wonderful tone and lacks the harshness that digital is famous for.
I strongly recommend pairing it with amps and speakers that can deliver strong bass to maximize the startling performance of this truly high definition cd/dac
