Rogue M-120 and M-150

I have had the M-150 amps for 4 years driving audio Physic Virgo's and now Martin Logan Summits. They worked well with both and Logans are a tough load 1ohm at 20khertz.
Great amp in my opinion also good opportunity to tweak to your taste by rolling tubes.

I had M-120's and upgraded them to M-150's. I felt the M-150's were better in every way. I drove Proac 3.8's with them with very good results. I tried many amps with these speakers:Classe CA200, Audio Research 100.2, Bells 350A, Accuphase E-406, and Plinus 9200. The Rogues were the best match for these speakers. They were a little hard on tubes. I had to re-tube them each of the three years I owned them.

Thanks to all for your quick replays. I first heard the 150's about two months ago at a friend's apartment that is similar to ours, a large open space which high ceiling.
He drove the Vandersteen Quatro and the combination seemed sublime ... Carreras voice in Ramirez Misa Criolla was mesmerizing! That's why I have been thinking about the Quatro as well. He had other amps and swears the Rogues changed the sound of his system. He also had the 120 Magnums for one year before he got the 150's and said they were a great value deal, sounding very close to the 150's, with some differences but not so noticeable. But the heating issue concerns me.

I am also concerned by Mag5000's complaint with Rogue's service. Anybody else had that experience?

I, for one, have had great service from Rogue.

I found Rogue service to be well above the norm, they even sent be a schematic for my 120's when I requested one for local "non-Rogue" repair service.

I had no idea what they would say when I called them, but I didn't want to ship two amps, all the way to Rogue for a simple repair...probably $150 shipping cost.

My local tech guy told me that when he had a couple of questions regarding the repair, Rogues tech guy was more than friendly...and answered all his questions.
