Good budget amp for Mirage M1

A used B&K amp can be had for that price. Also, for a few hundred more you could get a new factory direct Emotiva amp that has serious watts/current. My friend has one powering Maggies and it sounds very nice for the price point. Will run the Mirages easily.

I had the M1si, newer version, for many years and you are right they are power hungry. I started with an Adcom 545 (100watts) and ended up in the end with Mcintosh 500 watt amp. For $500 it will be hard to find anything that will bring the M1s to life, possibly an older high power Rotel or Adcom? As for your speaker cables try the Anti-Cable, Blue Jean, or DIY type as they will surely be a huge improvement over what your using now.

I used an Aragon 2004 Mk II for several years on Mirage M5si with very good results. While not optimal for the M1, it would be better than what you are using. An Acurus A250 would probably work well also. I second a look at the Emotiva amps in your price range. Stretch your budget just a little and the Parasound Halo A23 becomes an option.

I'm a long time owner of Mirage floorstanding speakers, including a pair of M5si's I've had for 16 years. You definitely want both power and current, and large gauge cable going to the woofer inputs. I use a 6-gauge cable run to my bi-wirable M5si's. I'd use *at least* 12-gauge wire with the M1s.

The factory specs for the M1 indicate a sensitivity of 83 dB. This is *low*. You need to aim for the most power and current you can get at your budget, preferably high current amps in the 150-200 wpc neighborhood. You can find used high current, high power amps within your budget from Adcom, Parasound, Rotel, older PS Audio, and--as mentioned--Aragon.

If you're willing to go a bit above budget, you can get a new warranteed pair of 200-watt Outlaw Audio M2200 monoblocks for $700.
