Stuff in neighbours basement moves at times...

The Logitech isn't bad for small small rooms, aka close to speakers.

This isn't a bad amp for the price: http://www.outlawaudio.com/products/7125.html

But if you wanna go louder, a sea of EP2500's in basically a server room would do quite well.

The class H is worth the price over the class A/B like the one I have.

So......... budget?
