I do not even own MLs (but I have heard them and love them and have always wanted MLs) and the only thing in my budget would be the "Source" line but I want to know before I go any further what these speakers need for amplification. Posts I have found suggest you can "get away" with a $2,000 amplifier. What I need to know is what is the minimum you need and how on earth can you find out if an amp can power a 4 ohm impedence speaker because amps seem to be rated in terms of watts. Would be used primarily for recorded music so I don't care if it has a tuner or surround sound and such.
