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

Hi

HiFi+ (England) latest issue reviews the M-150 very favourably. They say it's around 30% more expensive but you get twice the quality. Try to get a copy, it's worth reading. It's a beautiful magazine.

I own the 150's and what Mark says is all true. They run much cooler than the 120's and have significantly greater detail. And the very good cost/quality ratio still applys.

Thanks for the replies! I've decided to go for the upgrade, I'll be shipping my amps to Rogue tomorrow. I have an idea that I won't be dissapointed. I decided to have them leave the Magnum M-120 faceplates on them, I think they look better. The only downside I see will be having to go without my amps for about three weeks. I guess the old H/K AVR 7000 will get pressed back into 2 channel service for a while. I think I'll survive...

Have a good day
