Magneplanar 3.7 - recommended preamp and amp


I've owned the 3.6 speakers years ago and really enjoyed them. I want to buy the 3.7s and also need electronics. I have a budget constraint of 4-5k for a solid state preamp and amp. I'm okay buying 2nd hand. For those who own Magneplanars can you recommend gear within my price range? My room size is 16 x 21 and I don't listen loudly. I thought even an integrated amp might work (like the Moon i7). I'd appreciate hearing some ideas.

Thanks!

THEY NEED LOTS AND LOTS OF POWER. A DECENT AFFORDABLE AMP THAT SOUNDS GOOD ONCE WARMED UP IS THE MONSTER POWER MPA 2250 OR 3250 AMPS. NOT MADE ANYMORE BUT FOUND ON AUDIOGON . THEY ARE RATED AT 250 WATTS BUT ARE MUCH MORE POWERFUL INTO LOWER IMP.A GOOD PREAMP FOR THIS WOULD BE A GOOD TUBE PREAMP OF WHICH AUDIO RESEARCH MAKES MANY.
Atmasphere- thanks for your comments. i have used a tube preamp with a solid state amp and it worked fine together. I will look at this again for the new speakers. I will however be going with a solid state amp. I'll look into the Mogami wires.

Luckydoggoldminer1...Dude, turn off the all-caps! You are shouting at us. Totally unnecessary..we get your point.

I'm going to consider that you are new at this and are not just being rude with the all-caps. All-caps is poor internet etiquette. No more, please.
