My buddy is looking to buy an efficient amp, and I know that Mmats is known for there efficieny (of which I have experience with). He is about to file a claim through USPS because they left the last amp he bought outside his apartment, and it got stolen. It was of sentimental value to him, so he should be getting a fair amount back from it (at the very least, the $130 he paid for it). I am not sure how much he will be getting exactly, so if you guys just want to post any oldschool Mmats amps you have, that will help a lot. By oldschool, I mean the series similar to the d500.1 and older. I would also love to trade stuff for Mmats amps...I have some things like a Hifonics American Warriors Taurus X, Alphasonik MA2025, Audiocontrol 2xs, etc. I do not, however, have any money to spend, thus it will need to be a straightup trade. I have a lot of things that would be better suited to local trades, so let me know if you are local.
