Hi, I am presently using teh Yamaha E800 processor with bi-amped Audiolab units, and B&W speakers throughout. I have recently bought the Arcam DV27 DVD player, and am now wondering whether I should also change the processor or whether I have merely got upgrade-itis. Just wondering whether DD and DTS Ex are worth going for, or what other processors I could get to make a difference. Another question anyone know whether I would be better off using the Arcam internal decoding or continue to do the decoding in the Yamaha. Cheers, Dave.
