Well I am a few weeks out from getting my martin logan source electrostatics

, and I need some power on a budget to get them going. Regular recievers work ok, but these speakers are power hungry, and they need power to get the most out of them.. I was thinking I wanted a nice 5 channel amp, and a crossover, but maybe I can get another amp later for the surround sound... I want to get a nice 2 channel setup going first for a budget.
This will be the first time I have done home audio in a long while, and it is certainly the first seperate amp system I would be doing, so Im not sure about all the components I need to complete it. Im used to recievers having everything I need.
At any rate, can anyone give some budget 2 channel powerful amps to look at, and or crossovers. Thanks
