They sound impressive.
I want the four channel 250W x 4 [img]graemlins/headbang.gif[/img]

 

I'll agree that they seem to have impressive features but aren't they just Rockford's Type RF amp with a different heatsink?

Whether they are or not, I guess it just Rockford's way of selling their product to the "audiophile" market.

 

They are their own design I have been told, nothing of the RF line is in the MB line, they just own MB.....................

 

I got a chance to have a look at some of the Quart amps recently, very solid heatsink, the power supply is well isolated from the rest of the board to prevent noise issues, looks pretty nice. Have to see how they work though.
