I recently built a bipolar power amp with a high quality pot for a
volume control. I use this amp with CD input only in my "background
music" system.
My main system has a Musical Fidelity A1 amp at the centre of it, not
super-fi, but it sounds good to me. The A1 is smooth sounding and
involving, but bass performance is not it's strong point (though it's
ok).
The amp I built is different to the A1, a little clinical
sounding, but deep and firm bass. My question is - it wouldn't cost me
too much to build a second pair of amps, this would enable me to go to
bi-amping. What sort of differences might I notice by doing this? I
have to say that I don't need to do this, but I'm interested and may
try it for fun.

I assume by bi-amping you mean driving the seperate parts of your
speakers' passive crossovers with seperate power amps, as opposed to
using an active electronic crossover before the power amps, and no
passive crossovers at all. I'd term the latter "active", although that
usually implies the power amps live in the speaker cabs. However.
I would expect to hear more control, especially at low frequencies, and
greater seperation between details in the music throughout the band, by
bi-amping. This can be had to a lesser degree with bi-wiring, and to a
much greater degree in an active system. Whether this this will actually
sound *better* will depend on many other factors in the system, and may
ruthlessly expose any inadequacies in the source signal.
You may get a more learned discourse on this in DSSDEV::AUDIO, where I
see you've also posted this note.
Have fun.
Dave
