Fast? You want fast?
Atma-sphere OTL amps are amongst the fastest amps out there, and they do it so effortlessly that you at first may not even be aware of the speed...until you realize that you are hearing leading and trailing edges of notes that you don't even hear on the Spectral. Just bloody amazing...but...there is always a but...OTL amps tend to be a bit persnickity about speaker loads. The Zero autoformer alliviates most of the impedance problems though.
If slew rates alone mean anything, the Atma-sphere runs in excess of 600 volts per microsecond...and actually sounds like it. Great settling time is the other side of the equation; and most amp companies don't ever talk about that.
Spectral preamps are very fast, and the Atma-sphere preamp is synergistic with their amps.
