Denon POA-1500 Stereo Amp

I am going to demo a semi vintage(80's plus)Denon POA-1500(150w/ch) stereo amp this Sunday. Found on C-list($235.00) and it appears from photos to be in excellant condition. I will be using it in conjunction with a Marantz 2252b to power a pair of Klipsch Forte's. I might consider using my Luxman R-115 as the preamp with this amp. Any thoughts will be appreciated.

Thanks,
Bill
