Rogue M-120 and M-150

Alessandro...I owned Rogue M-120 and enjoyed them very much. I used them with Merlin Vsm-Mxe, Sonus Faber Cremona, Speaker Art, and many others. They are wonderful amps that should work quite well with your current speakers as well as Vandy Quatro. My only problem was keeping them running. Unlike many others on Agon who have had great service from Rogue, my experience was not good. Service was expensive and very, very poor. They never were able to get them to work. I had to find a gentleman in L. A. to repair them. Again, I am sure most have good luck with them, I didn't. FWIW, I bought them in the beginning on the recommendation of a friend, and his failed as well. I have heard great things about the Rogue M-150 though.

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
