Amp for Mirage M1 Si's??


Picked up a pair of M1's and am wondering what might
be the best amp for around $500-$1000 or so.
They are very power hungry it seems. I have a 200 W/PC
integrated that by itself is on the warmer side of nuetral
and these M1's seem to still be a little under powered (83db)
and on the darker laid back side. What would give these
some sparkle & kick?
I like the overall potential of these to pursue the
right amp.
Room is 20x20x12

Any suggestions greatly appreciated!

Spikes were definitely standard and bundled from Mirage.

The best sound I hav ever heard was M1si driven by a CJ EV2000. Unfortunately the Evolution 2k is out of your price range but the mf series is not.

I have to admit that the class d recc makes a ton of sense too.
I have a pair of M1si, try the Rotel RB-1090 380watts. I used this combo for about one year with great results, then upgraded to the Bryston 7bsst2 with even better results, but also a large price increase. Dollar for dollar the Rotel RB-1090 is a excellent amp for the $1000 range used, it can not be beat for the price.
I have gone through quite a few amps with my M-1's. Adcom 565's,Bel Cantos,Parasound,a few different ice amps, and a Proceed HPA2 which is driving them now and they sound just wonderful..again its what sounds best to you...but a fun ride getting there...

I had a pair of M3si many many moons ago and I drove them with an Adcom GFA-555 and then a Krell KSA100s with very excellent results.

These are very power hungry speakers so if I was looking for an amp now, I would investigate class D ... probably best ROI.
Gee this thread brings back memories. I had the original M1s, the first year it came out. The best I've ever heard them was with Atmasphere M1s tube amps, but way out of most peoples price range. I think you might have trouble getting the best out of them in your price range unless you are going to buy something used. I had them with Threshold SA3 50watt class A amps that did a great job on them. I think SA3s go for around $1500 used, but you might get lucky and get one near your price range in this economy. I think any good tube amp with at least 50 watts can drive them, but you really nead 100+ watts for them to shine. Oh yea, McIntosh's sound great on them, if you can find a used one in your price range.
