In my system the Musical Fidelity M1 CDT sounds better than the April Music transport, to me.
The Musical Fidelity has an airier, more illuminated, more like music sound. Slight, but there. I went back and forwards on them, one day one would sound better than the other to me. But after the dust settled, putting the April Music back into the chain was not as satisfying as the Musical Fidelity. Though I could live with either and would have been happy. Until I heard the Jay's.
The difference between the Jay's Audio and the April Music or the Musical Fidelity, is not slight. More weight, more information, more dimensionality, more everything. It just sounds as though the signal was better preserved before it hit the DAC.
I'm sure there are better transports. I imagine the CEC TL0X is better, and the Audionet Planck might be better. But I doubt they are so much better that it would make sense to switch. But I haven't listened to either, so I could be very wrong. And let the record show that I would gladly take a CEC TL0X over the Jay's. However, I see no reason to want a different transport for redbook replay.
