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.

Thanks, Ralph. I saw them at Audio Perfection in Minneapolis Minn. Probably not far from you.

Driving high impedance speakers the Atma OTLs are among the few best amps I have ever heard or owned. The other amps on this list were at least 5 times the price of the Atma-spheres.

jsautter the MA3s are $147,000. That is no joke. But, it takes 3 months to build the entire very large 4 piece set. I do not know how many people are involved in the labor but I would bet it is at least 4 if not more. Given that and parts and you can see why they cost so much. Also Mr Karsten insists they are just fine driving loads down to 4 ohms. 
Now we can ask Mr Karsten, Ralph, why would an employee's set of M60s be red??

I would speculate the answer to be "because he can."  Just take the standard M60 case work to a painter / powder coater  and return it to the shop for assembly.

@mijostyn  Actually MA-3s can handle loads much lower than 4 ohms! The MA-1 and MA-2 can do 4 ohms as well.

That employee just wanted red...
