I have 2 MMats D200hc's. perfect working condition and great shape aesthetically.
They have the same power output as the 300 except they run at 1 ohm instead of 2 ohms.
(but can be burped at .25 with the right amount of rise otherwise .5ohm daily. I've never ran these below .5, ever. I have had this pair for over 9 years, most of the time they've sat in the closet)
I want 600 for the pair, includes shipping.
