That amp is now with me. As I have posted in a different thread, the output of channel B was not soldered on the SpeakOn PCB. After removing it and soldering the connections properly there is still difference in volume. But it seemed less than a 6dB difference, and no drop outs (only tested for 10min)
Admark will send me the PCB they think is faulty (channel pcb they said) but if there are other suggestions to check please let me know!

Update: Output PCB received free of charge. Replaced the PCB and the amp works fine! Great customer support from Admark
