Best amp for Magnepan MG-12

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.

The Burson PI-160 does a good job with maggies. Clean bass, nice mids and highs.

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!

Thank you very much for your advices guys. Really appreciated it. I am still looking even if I just bought an Acurus A250. I will probably get a tube preamp with it and try it. For now, still using the Jolida. Not bad (giving the size of my room (10x17), but want to try something different.

Thanks again

As a follow-up. I have the Acurus 250 with an Anthem PRE 1L. Excellent, except that at high volume, the Acurus get really hot. Will try this set up for the next days.
