Thanks for your response cytocycle. I am considering these to replace some high powered tube amps. I like the crystaline you are there mid range that tubes seem to offer. My speakers require an amplifier that controls the lower regions. My current amp pretty much satisfies the requirement but I would be interested in changing if I could reduce the tube maintance,as my amps currently have 28 tubes, and retain the sound qualities that I like of tubes. I am sure that by your feedback as well as all the reviews I have read that the M1.1's sound very good indeed.
Lamm M1.1 hybrid comparisons to tube amps
I would like to hear from anyone that has experience comparing these amps to other high quality tube amps such as Lamm's own ML1. It is my understanding that these amps are supposed to have a very tube like quality but with the advantages of solid state.
