I am a proud owner of an ARCAM A85 integrated (excellent amplifier). I have recently had a chance to have another one for a bargain price. Now I would like to use one of them as a power amplifier and biamping my Triangle Celius speakers. Is it possible to do this? Is there any difference between using A85 as a power amplifier and P85 power amplifier? And which method is better ; vertical or horizontal biamping? Regards.
