Audia amplifiers- comments?

Audia has a very refined sound with tremendous bass response. Smooth yet extended highs and lows. I've owned Krell KAS2, FPB series (numerous), Goldmund, Brinkmann and a slew of other exotic amps. Still own Lamm amps. Audia is an excellent amp for its second-hand price. Well made, wide bandwidth, silent. I still have the Flight 100 and would use it if I still had speakers it could power (which is most everything except what I have now).

The Audia specs are -3dB at 1 MHz and a fast slew rate of >200 µS. I believe that this constitutes wide bandwidth (as well as high-speed). Many solid state amps offer a frequency response that is -3dB at 160 kHz or so. Many solid state preamps offer frequency response of -3 dB at 200 kHz. I imagine that the choice to design for high bandwidth is to allow amplification to pass a higher kHz square wave without ripple. Spectral and Goldmund are well-known for touting this design feature. I will reserve comment for the audible characteristics of such a design.
