I got a set of HITACHI 8500 MKII amp, pre-amp, cd player and tuner , for $30, amp needs some repair, but I got another set for 100 with boxes from the original owner, this set works, the sound is amazing, crisp, clear and loud, and the unit looks beautiful. never knew Hitachi had such an amazing product,I got them for the large meters and discovered it's sound quality.
