these are actually MA6100s not MA500s, the specs are the same for both models I just listed the incorrect model number. The MA6100s model replaced the MA500s
$450.00 obo plus shipping
This ad is for Four Marantz MA-500 THX Ultra Monoblock amps. 125 Watts into 8 Ohms, 180 watts into 4 ohms. The LED's do work, Red when in StandBy and Blue when On. These amps can also be setup to switch between "on" and "StandBy" with a Video Source from your receiver / PrePro or from a DVD player. These amps are stackable. I had these amps in a cabinet of their own along with the pair of MA700's I recently sold but recently took them out in preparation of getting my new amps and new component rack.
I am currently using these Four amps for my Center, surround and surround back speakers but I will be upgrading. I bought these from a friend of mine about 6 months ago, he was the original owner and used his system casually. I like the amps but I am upgrading to Anthem multi-channel amps. I would prefer to sell the four as a package but I am willing to sell them in Pairs ( $250 for two )
I do not have the original boxes but I will have them professional packaged.
You can check my feedback on ebay as well( ts108 )
