Best amp for Magnepan MG-12

Just get a Magnepan MG-12. Using actually a Jolida 502B. I feel that the Jolida doesn't have enough power and that I can get a better result with a more powerfull amp. Willing to go with an integrated or separate, tube or SS and lookink for suggestion/advice. Budget: around 2 000$.
I have a pair of these in a 12 by 14 room. They are positioned about 6 from the short wall and my ears are about 3 feet from the opposite wall. I am using a Music Hall Maven receiver that produces 100 watts at 8 ohms (not sure what the 4 ohm rating is). It does amazingly well with them. But I am using very high end source equipment like $5000 Digital front end, $6500 analog front end. (source is king) I was used to amps like Linn Kairn/Klout, ARC VT100 mk3, Mcintosh C2200/MC402 before I was forced to sell my equipment and start all over again (didn't get to try these with the MG12's though). The Maven might be a problem in a much larger room if you're wanting really high sound levels though. I bought these for apartment living since they are not huge bass pumper-thumpers. Although the bass seems just fine for true musically virtuous songs. Probably won't satisfy bass slam adrenaline junkies though. I'm wondering myself what to upgrade to but only for rhythm & harmony quality improvement reasons. Thinking of going back to the Linn Kairn/Klout combo for this. The klout will do 160 really high current rock solid watts at 4 ohms. I see no reason to upgrade from the maven for power/loudness reasons. It's nice to have speakers that have no problems with the critical aspects of midrange. That's the part that really matters.
You could get a used Bryston 4B-ST or Wyred amp and still have change left over. 2 very nice sounding smps.
Try an NAD C 275BEE stereo amp (or the integrated pre/amp, C 375BEE). Used C 275BEE amps can usually be had for around $700 here on Audiogon. I used this amp before I purchased my Cary 500 mono-blocks. The NAD is excellent and has ample power, current, and headroom for your Maggies. It sounds very good and is a definite steal for the money!
