Biasing Classe DR 25 power amp

Does anyone know what the factory bias should be set at? I thought about setting it a little higher for a warmer sound.Please any info would help!
Contact customer service at Classe. I asked a similar question and a factory tech sent me the biasing procedure for a CA-150.
Someone mind clarifying for me what you mean by "biasing?"
When I had my DR-8's they were set about 18ma per transistor (times 4 for the DR8) and I was told max current was 24ma. I set them at 22ma to be on the safe side. The higher bias did make the sound warmer/richer.
