fatman 182 / 252 amp sound issues

[macipod]

hi as anyone that owns one of these amps noticed that there is a difference in the sound that comes out of each channel meaning one is clear and the other is slightly dull it is not the speaker as I have try different speakers cables interconnects and the source thanks

Havent heard them but obviously that is a fault, both channels should reproduce to the same standard.
