Best amp to match with Martin Logan Source spkrs

I came across some ML Source spkrs that my son bought from Frys for $581. I love the sound even with my old Pioneer Elite 80w. I had 1980s Thiels that need new tweeters and mid and thinking of selling them. I want to keep the MLs since I love their clarity and transparency. I'm well aware of the critical room positioning. My question is has anybody matched this speakers with an amp that will make them sound superb. What do you guys think of this entry level ESLs. I'm starting to replace my old sound system and would like to build around them. Oh Planning to spend around $2-3k total for spkrs, amp, cable and cd player. I know it's not much for an audiophile, but it is what it is. Thanks for your comments
