The Fastest most musical amp

The slew rate is the measure of an amplifiers ability to respond quickly (fast) to the musical signal. It is interpretive based on the power of the amp: a 50 wpc unit can have a lower slew rate than a 100 wpc unit and still be "sufficient". There's alot more to an amp than that, but that's part of "FAST."

Dismalonyx, if you're looking for a completely natural presentation possessing good speed, agility and tonality without sacrificing dynamics or the "life/energy" associated with great music, you should consider Blue Circle's BC8 monoblocks. They're very fast and are one of the most musical amps I've listened to! Regarding a preamp match, I think your musical preferences would need to be known before making a good match... the good news is that there are a number of solid state and tube preamps out there that sound great with the 8s.

Let me know if you'd like to discuss!

My recollection is that Spectral and Goldmund have the highest slew rates among solid state amplifiers (1,000 volts per microsecond, I think). Atma-Sphere is certainly among the fastest tube amps, with a slew rate of 600 volts per microsecond. Note that 50 volts per microsecond is a typical solid state slew rate, and 25 volts per microsecond is probably typical for a push-pull tube amp.

Since I'm an Atma-Sphere dealer that's where most of my experience lies as far as "fast" amplifiers goes. Atma-Sphere amps really like to be driven by Atma-Sphere tube amps, using balanced connections. I would expect likewise that there's a very good synergy between Spectral amps & preamps, and between Goldmund amps & preamps.

I would not see the Spectral/MIT combination as some kind of sacred bond. I bet Spectral amps sound just fine with other high-quality cables.

Best of luck in your quest!

I agree that fast + tubes equals Blue Circle. The Naim gear is fast also...

Duke: you can actually damage Spectral amps, in particular the newest ones, without MIT/Spectral cables. The MIT cables act as a low pass filter to eliminate any HF hash getting through.
