In the past - I've been with the understanding that nothing should be placed in the a/c circuit before the power amplifier. With these new Balanced Power a/c conditioners - has that changed? I'm considering the B-P-T products. As an example - with the use of multiple Aragon 8008BB amps for a HT system - would using a BPT product be a detriment to the amps capabilities? What are your opinions?
