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.

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.

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.

@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...

Ralph. That color was a deep crimson and very beautiful. You should keep offering it as a standard color! IMO.

I would love to hear the S-30 on my Avantgarde Duo XD. I bet it's wonderful. My speakers are 18 ohms at 107 db. I just don't know if there would be any audible noise from my speakers without a signal. It would be fun, I'm sure.

@joeinid Horns aren't a problem including AvantGardes- a review is on our S-30 page. We have an adapter we use to reduce the gain of the amplifier for use with really high efficiency loudspeakers (it replaces at tube in the voltage amplifier). It also reduces the noise floor.
