keep & use the Luxman, if you have problems how to hook them up, ask us, or your dad

(if it's any hint, if you want to connect you pc to the luxman, or the tuner, the connections are at the bottom of the amp.)

I don't know much about the jamo's, but I haven't been really impressed with their products lately...

I'd think i'd get new speakers though, but DEFINATELY use the luxman for now, you'll at least already have stereo.

so: this is what I'd do now:

use luxman and get a pair of decent speakers
get surround receiver & use the old Jamo speakers as rears
get center & subwoofer
enjoy

Keep them spinning,
Bert.
