Hi! I'll try to be as specific as possible, although I believe the interest is broader. My setup consists of Wharfedale Diamond 155 + 101c + 121, connected to a 7-channel combo Nakamichi AV1 + AVP. Since I have two free and assignable channels, I was looking into bi-amping. The processor can apply a digital filter in order to separate the frequencies for classic, horizontal, active bi-amping, but ... I was wondering if doubling front-channel signal through y-cables and doing a passive bi-amping would give better results and/or it would be a better long-term solution, relying on the internal cross-overs. I am aware that I am using the same power supply and the modules are identical, so this wouldn't be a true vertical bi-amp setup, but, on the other hand, I am also looking for a analogue-only preamplifier. The processor, unfortunately, re-digitizes analogue input, which is a shame because I was already using a better USB DAC with my PC. So, essentially, I have two unused power modules [email protected] on the amplifier and two bi-wireable speakers. How could I make the best of this?
