Atmasphere amps trustable?


Tube world, a big world, then I came acorss the Atmasphere on the net, looks different from those common tube stuff... kinda weird, the M-60 uses 8x 6AS7G output tube and 4x 6SN7 driver tube per channel, where're the rectifier tubes? Plus they're so-called OTL, sounds even more weird.

I have owned M60s for 17 years.  I first purchased them as a kit, and then I had them upgraded in 2007.  I have changed the tubes once in all that time.  They were absolutely reliable even though I drove some difficult loads with them.  I used them to drive my Quad 2805s.  I also want to say that heat has never been an issue.  The 100W Wavestream Kenetics Boxters that I am using now to the drive the Quads generate much much more heat.  They are standard push-pull amps based on 4 6550s (KT88s) each. 
Well, I can tell you they are one of the best amplifiers and pre-amps in the audio world if not probably the best available at down to earth prices. In my setup they have outclassed many more expensive Tube gear.
Atma-Sphere Customer service is one of the best in the industry and warranty upgrades is too. Iv never had any issues owning Atma Gear or having experiences with Failure. 

Ralph is well respected around these forums and always answers emails with any questions you may have.

It may be advisable to research about Atma-Sphere posts first before you make such comments about the company. They have been in business longer than I have been alive on this planet. I spent months researching about Atma-Sphere many years ago before I decided to place orders for a full setup. Comparing them to VAC, BAT, CAT, PASS and many other audio companies I never have had much satisfaction except with Atma.

Proper matching is required for the Power Amplifiers to Speakers, however even the Pre-Amps can outclass many more expensive audio gear even 4 times its price. Something to ponder on. If your in the USA, I would urge you to fly over to Atma and hear for your self.


I’ve seen a lot of people site the fact that Atma-Sphere’s products are sensitive to speaker choice. I’m currently looking at buying Zu Soul Supremes and they are a very high efficiency two way 16 ohm speaker. The s30 is on my short list of options and the only OTL as all other considerations are SETs.
I believe Atma-Spere is going to be at RMAF so I can definitely talk to them there, but I was wondering if any one would have input on the subject for me?
What are you guys running/liking with their products?
Clearly the troll that started this thread has gone underground where he belongs. I sure hope he stays there.
@cottguyWe've had good luck running ZU loudspeakers at our facility; in terms of efficiency and impedance they are very similar to the loudspeakers we will be using at the RMAF.
