Spectron Musician II -- deep bass perfomance??

I am considering purchasing this amp, and have read all the "raves" but was just wondering how this amp performs on the bass-end of the music scale?

I'm a dyed-in-the-wool "give me a big block six or eight over a turbo four any day"... "just-don't-see-how-an-amp that doesn't weigh at LEAST 100 lbs.-gonna -slam-my-face-with-bass" kinda guy, and would like to hear from owner's of this amp as to how you feel it compares to the "big boys" in the deep-bass/bass-control area.

Thanks to any & all.
