Looking for Amps with Martin Logan's Aerius i

I just purchased a pair of Martin Logan's Aerius i speakers. I know what kind of sounds I'd like to have in my living room but I'm such a novice in electronics. Any suggestions as what pre/power amps may match well with these speakers? As one might suspect, I have a very low budget of no more than $3,500 range. Thanks in advance for anyone's advise. Andy
