Biasing Classe power amps

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!

I'm very pleased to hear this news LUNA. "And then using hearing for fine tuning the center balance". Yes, in fact this is the only way to achieve "in home" results. This is one reason that drove me to take matters into my own hands. From the factory, new out of the box. The channels will not sound 100% equal in your room. They set the bias precisely, but the passive components vary in "sonics". You will have to technically set each channel at a different level. That is why the spec is +/- 1.5 to the reference. One channel may be -1.5, the other +1.5 and sound identical.
Realize that the bias effects the gain of each channel. And probably the input sensitivity as well. Classe is not the only amp that benefits from hands on bias setting. Good job- enjoy your monies worth.

I have a CA-300. It isn't warm and sound cool and sharp for long time using.
I would adjust amp biasing. Let me know about how to bias.
If anyone have a setting manual, please send me mail Or teach specific method.

Thanks.
