I actually used the Jolida as a transport for awhile with a Nixon Tube Dac and thought it was a nice upgrade vs. the Jolida as just a CDP. Note: I tried almost every tube imaginable with the CDP and was happy for many years.(Mullards,Telefunken,RCA,GE,Sovtek,JJ,etc).
Then I happened to borrow a Audio Note CD Transport ZERO ($550 used $899 new, but discontinued) and was surprised at what a positive impact it had on the overall sound. Basically everything just sounded better...I wont go into all the audio blah blah. The Jolida is just an ok placeholder until get something better IMHO. My 2 centz
