Over the past few months I've replaced my consumer grade system with a system that nibbles at the lower-end of the audophile world:
NAD C320BEE Integrated Amp
NAD PP1 Phono Preamp
NAD 521i CD Player
Ascend Acoustics CBM-170 Speakers
My old Denon Turntable
Grado Red Cartridge
I was basically pleased, but there was a definite lack in the low end. The Ascend Acoustics are impressive, but there's just no way they're gonna dish out enough bass. So, I went for the lower end HSU sub and man oh man what a difference! I've never had a powered sub before, and I know there are bigger & better ones out there, but this definitely puts some punch where it was lacking before! I need to play some more with placement and settings, but I think I'm done for awhile....
