The amp is a 5 channel Marantz MM9000 THX Ultra certified and has been sitting in a box for the last six months, I just finished testing it and it is in great condition. I use to use it to power my Onix speakers, but then I downsized and just used my Pio Elite receiver. So I though I should sell it and let somebody enjoy it. It is rated conservatively at 170W at 8 ohms for all five channels and it also comes with the users manual. The HD receiver is a Samsung SIR-TS360, it is for over the air and it is also a DirecTV HD receiver. Manual and remote from DTV comes with it. SOLD: Amp, I am asking $550.00 OBO plus shipping from 90650. HD receiver I am asking $250.00 OBO plus shipping from 90650. Pics are available upon request, e-mail me at [email protected] for them.
