Thank you guys for your advise. I have also got the people at Classe to show me how to bias my CA401. I have set it to around 30mV(max. recommended). And then using hearing for fine-tuning the center balance.
The amp sounds very different form original configuration. The dealer set it on 24mV. The sound is rounder, less forward and much warmer. It fits very well with my Thiel 2.4
OTHER OWNERS OF CLASSE AMPS SHOULD GET ADVISE ON FINE TUNING THEIR AMPS TO SUIT THEIR SPEAKERS. THIS TWEAK WILL MAKES YOUR AMP WORTHS ALL YOUR MONEY!
