Why upgrade?
When your system doesn't sound good, u don't feel good;

Solid-state amps with their inherent higher-damping are uniquely
suited to control the higher-mass of real woofers (10" & greater).
If you love tubes, bi-amp with tubes on top, solid-state on bottom.

AllegroSound electronics are never hard-started,
ensuring maximum life from the electrolytic caps,
and not run with excessive bias and resulting heat
that damages caps, resistors, transistors, ic's, tubes
and solder connections, avoiding costly repairs :-)

rare Collector's Chrome Edition + AllegroMods.
The last amplifier you will ever need...or want!
" of the most delicate-sounding amplifiers I have
encountered, whether tube or solid-state...resolves fine
detail superbly...has the microstuff in spades..also has
the macrostuff...does full-scale dynamics as well as any
amp I've to make small speakers sound big...
there were times I could swear I was listening to single-
ended triode tubes...string tones were particularly clear,
clean, and grain, grit, or spit...great soundstage
depth and width...sense of ease, of unlimited dynamics,
of music's often explosive power...I can find nothing to
criticize about this amplifier's sound or behavior...the true
test of any component is how you feel when it's time to
send it back; I asked for two extentions, then finally had
to let the boys retrieve them...the finest solid-state amps
I've had in my system.
