What are folks opinions of these amps? In particular i am looking at the MF X-A2 integrated amps. There are a few on Ebay and seem to be at good prices. These would be to partner with either B&W 684/683 floorstanders or the B&W 603 S3 floorstanders (which i'd get off Ebay also) I mainly listen to bassy, electronic music (Leftfield, Underworld, Layo & Bushwacker, Daft Punk, Bob Sinclair etc...) but i am also a fan of Pink Floyd. Would this amp provide me with good, clear, punchy and deep bass?
