Rogue Audio M-120 vs M-150

Hello;

I've had a pair of Rogue Audio Magnum M-120 amps for about 18 months now and drive them with a Rogue Audio Magnum 99 preamp. I've been extremely pleased with them, to say the least. Well I recently called Mark of Rogue Audio to order a new set of output tubes and he made me a great offer on upgrading my amps to the newer M-150's. Unfortunately there is no place near me where I can listen to the M-150's so if I upgrade it will have to be without hearing them first. Mark thinks I would be happy with the upgrade and he hasn't steered me wrong yet, but I was hoping to get some additional input before making a decision.

Mark tells me that the newer design produces far less heat, has about double the output tube life, and is more dynamic and transparent. Given how pleased I've been with my current amps I'm more than a little hesitant, but if I can take my system up a notch at a reasonable price, why not? Any input will be greatly appreciated.

Have a good day
Brad

It's a good idea to pull the tubes out regardless.

I've received the amps twice (once on purchase, second time to have an errant resistor replaced on one amp), each time they had been knocked around enough to break the tubes' "stems" off inside the sockets.

This did not affect the functionality of the tubes, but does make installing them more difficult. I ended up marking the base of the tube to make correct pin alignment simpler.

I don't mind getting them with new tubes; I'll probably play the 88's for a few months and then put the GE's back in.

Kind of off topic, but does any here know if the M-120 or M-150 have enough power to drive a pair of Salon? I read many great thing about the Rogue Amps so I would like to get a pair. But the Salon require a lot of power to drive it. Thanks for the help.

I don't know how much power you need but, In triode mode, the amps don't start to clip until right around 100 watts

Yiroryos,
Many (myself included) have found VSR speakers to match very well with Rogue gear.

I'm using VR4's with the upgraded drivers. I can only comment on their match with the 120 Magnums, which is wonderful. I am looking forward to their return as 150's.

As a plus, Albert von Schweikert, like the Marks at Rogue, will answer emails, return your calls and is a gentleman.
