Amp for Mirage M1 Si's??

I recently brought my M-1's out of storage and paired them with Parasound Halo JC-1 monoblocks (400 wpc.) They have never sound better! I was very impressed. A bit over your budget, but goes to show what can be achieved.

Thanks every one that's what I'm looking for! So maybe
a Spectron or Parasound might work. Any thoughts on how
Krell might work?
I have been playing with and getting some positive results
with just swapping PC's. Also I initially had them to
far apart for my listening position. Just 1/2 inch in
both ways really locked in the solid wall of sound.
Any thoughts on spiking them?? I did not get any with
them but wonder what effect they may have on the bass?
Anyway thanks for the advise and keep suggestions coming!
Looks like I will have to try & raise my budget somewhat.

Spikes make a major improvement! A necessity IMHO!

Brand new--they came w/spikes---Don't expect much in bass definition w/o spikes.--Get U some.
As I remember from the manual their setup instructions were "spot-on"--Something like 3 to 3 and 1/2 feet back and sides for unbelievable imaging.--Of course that was for the 3si's---I would also at least try the short wall. My short wall is wider than your 12;wide. Mine is 14.6 wide and that worked well.---(That rear tweet loves proper reflection.)

Thanks Avguygeorge,

I have mine right at at 3'4" feet off back wall at the moment.
And they are 9.4' apart center to center with about
2" of toe in or so. I have a 46" LCD in between
(Which I know does not help) and a big tree behind
the right speaker. Center image is pretty darn good,
but wonder if going closer together might make it better?
We'll see.
Anyway, thanks for the advise, will try to find out
what size spikes I need and get some.
Another thing I failed to mention, is I am using my Blu-Ray
player since I sold my Naim CD5i, and thought I could
live with it but will have to get another cdp.

Thanks,
Bob
