I recently took the plunge and decided to biamp my dynamic speakers, and I can
report that the results are pretty wonderful. After using solid state for years
(good solid state), I've now gone with a set of push-pull triode monoblocks for
the mids and uppers, and left the solid state amps to deal with the 15" woofers
on my speakers. I feel that this configuation has made a huge difference, even
before I've applied any tweaking whatsoever to "optimize" it. The sound seems
much more life-like and dynamic and I perceive a deeper soundstage. I suppose
you could call the sound "lusher" than before but I mostly perceive it as an
absence of a trace of brittleness, or a filling out of the mid and upper
frequencies. A recent SACD (Jorma Kaukonen on Sony) yields sounds with an
organic, "fat" quality with clear a sense of clear delineation of individual
instruments and rich higher harmonics. Whatever it is, it suits my tastes and
it has changed greatly my understanding of what my speakers "sound like". I
certainly think it's a worthwhile option for people who are considering changing
amplifiers entirely, or replacing their speakers. I can also report that,
depending on your equipment, it is possible to get very satisfying biamping
results without adding external crossovers, modifying speakers, etc.
