Eugene81 - maybe the brightness you were experiencing with the AP1 was a system voicing issue ?
The JK SPDIF mk 3 is indeed smoother sounding tha AP1. However, in my system, the JK SPDIF was actually too laidback, lacking in sparkle and ultimate midrange resolution to the best converters I tried.
I have tried in my system 13 different USB converters, including EA ORT 5, JK mk 3, AP1, M2Tech Evo (with and without the battery PSU and external clock), M2Tech HiFace 2, dCS U-Clock, MF V-Link, Halide Bridge etc.
Devilboy - which M2Tech converter have you tried ? I have tried M2Tech evo and HiFace 2 and didn't have the issues you are describing.
