Mirage M1 Speakers.

Thanks for the info. I'll pass it along to my friend.

I owned M-5Si years ago. They do like power. I used an Aragon 4004 on them and they paired very well. That amp is long in the tooth. What kind of budget are you talking about. If you could swing something like a Parasound A-21, it should work well.

One of the demos that really caught my attention years ago was a pair of M-1Si vertically biamped with a pair of Krell KSA-250s. That demo was what convinced me to buy the M-5Si. 

Agree with the above.  Had a pair of M-5si and they were driven beautifully by a Rotel 990 power amp. Hard to believe a pair of 6.5" woofers could soak up all the juice the 990's put out.  Great combo. 

My friend likes buying vintage stuff that doesn't cost a lot.

Yea, I have a pair of Mirage M1Si speakers powered by 2 B&K monoblocks and connected with Kimber Cables. It’s an amazing setup and really fills my big living room with 20’ ceilings. But as I look to downsize, I am considering scaling down. I just don’t know what the market is for these behemoths. But they are certainly beautiful and sound amazing! I am running them through a B&K MC101 preamp.
