Anyone Here Have Atma-Sphere Amps?

I find these amps very intriguing and was wondering what people with real experience think. I have read all the reviews
which are generally excellent except for some reason Stereophile has not reviewed them as far as I can tell.
The main question I have is how often if ever do you blow a tube and how long are your tubes lasting. Do you have any quibbles. I would love to find an MA 3 owner as that is one ballsy amplifier. There is no such thing as overkill when it comes to power amps.

I own the MA-1's and MP-3, both are great pieces of equipment.
Also, Ralph Karsten is one of the best manufacturers in the business. There is another discussion regarding Atmasphere and Ralph here on Audiogon.
As far as tubes go, I haven't had any issues with my amp for almost 3 years. (Though the preamp needed a new tube recently). The nice thing is that I can call Atma and get someone to help troubleshoot.
