Hello,
A few months ago I got a pair for $45.00 at my local thrift store, and was advised by the good Brothers on this forum not to use my Marantz receiver and that was good sound advice so I set about to get a seperate amp and pre and finally found something to drive them, they are just fantastic to listen to but are not as aggressive as my 4311's, but the seperation they give out is wonderfu. get to the Infinity side in the pulldown or type in the search window, you may find the manual. These guy's are very helpful and know their shizzle. Dont forget to say thank you!!!
