Many Krell and Classe amps I have heard over the years sounded
particularly "fast" to me. Don't know their slew rates. I tend to
associate fast sound ie a combo of high slew rate and matching ability of
speaker transducer to respond accordingly with a high capacity for
delivering holographic sound. Low mass transducers like electrostats and
planers seem particularly amenable for that. Dynamic drivers operating in
Walsh wave bending mode also seem good at this to me. Mass and inertia
associated with typical dynamic transducers are the biggest barrier to
achieving fast sound much like it is with a phono stylus transducer.
I don't know a slew rate spec for the bel canto class d amps I use but they
are ice power based and the holography is quite high. Shockingly so when
I heard them the first time compared to amps I owned prior. As class d
amps continue to improve I wonder if their ability in this area in general
continues to go up perhaps even raising the bar beyond other design
approaches?
I've read some diy discussions asserting that slew rate specs are irrelevant
for class d and perhaps some other amp architectures much as are very
high damping factors in most cases. Would not surprise me but I am not an
ee so dunno for sure.
I'll take al's wise advice and not worry about it much and just be happy it all
works and sounds as good as it does.
