Few questions for Arcam. 1. Does the AVR300 have identical power output stages for all 5 channells? 2. Are they transisters, IC's or a combination ? 3. If they are different, the quality of the rear effects amp will not be as good as the front amp. Therefore is it better to bi-wire than bi-amp an avr300. 4. I have an old 8P. will it be better to use this as the amp for the high's rather than the rear effects amp?
