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 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. 
Ralph,

Thank you so much for your response. I did not know that. I’ll go back to your website and read the review.
