I kinda considering bi-amping my speakers but i'm thinking of two possible approach mainly because of cost to prevent investing in two systems, i.e. for 2 channel stereo and hometheater. The first one is to use two sets of two-channel amplifiers and the second one is using an AV receiver like the Denon 3805 wherein i would use 4 channels (left channel {left front + left surround} and right channel {right front + right surround}). Had anyone reading this tried this setup before? I love listening to music but also watch DVDs. Multi-channel sound is not yet in with me. I also use sound improvement gadgets like equalizers, exciters, expander, etc. inserting this on the signal path is quite difficult and a challenge particularly for AV receiver setup. On using two stereo amps, my problem is using the subwoofer via the line input. The volume of the sub cannot be controlled. I'm not aware of a two channel amp with sub out and with volume control that adjust together with the mains like what AV receiver does.

Appreciate your thoughts on this. thanks.
