I just put a Jay's Audio CDT2 MK2 into my system, replacing a Musical FIdelity M1 CDT, and an April Music Stello CDT100. The jay's is MUCH MUCH better than the Musical FIdelity, and the Musical Fidelity was better than the Stello, to my ears.
The build quality on the Jay's is incredible, so that might be part of it. But the build quality on the Stello is better than on the Musical Fidelity.
Transports matter.
