Rogue M-120 and M-150

I have a buddy that had 120's upgraded to the 150's and there is a very noteable improvement. Pretty much an improvement in all aspects. Well worth the extra money for the 150's, IMHO. He is driving Vandy 2ce Sig with them.

One of our members owned the Rogue Zeus, Rogue 150's, and Rogue 120 Magnums...he stated in a post that the 120's were the best sounding of the bunch. He sold the Zues and 150's, and went back to the 120's. (you can do a search for that info)

I have 120 Magnums driving Apogee Duetta Signatures, or Apogee Stage...both sound wonderful with the Rogues.

That said, I would probably get the 150's for several reasons.

1. The 120's run very warm
2. The 120's are hard on tubes
3. The 150's don't run as warm
4. The 150's aren't hard on tubes

I honestly doubt, that there is much difference in sound quality, between the two (150's/120 Magnums)...I suspect the 150's are the more reliable design though....given the factors I mentioned above.

Good luck,

Dave

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?
