There were so many good bits on the milbert web site - but I really appreciated this one...

What's the rating?
30 Watts per channel, 20 Hz -- 20 kHz, -3 dB, 3% THD Some owners have reported that the BaM-235ab's "30
tube Watts sound much more powerful" than comparably-powered amps. This is often attributed to the
soft-clipping nature inherent in its design. Unlike transistorized amps which smack and crackle with abrupt distortion, the BaM-235ab exhibits graceful, smooth overdrive into clipping.

Spec’d at 3% THD - just think how bad it might actually measure? Seems unlikely that noise would be high enough to even be much of a factor... or maybe it is that bad...
