In Reply to: Question regarding Futterman vs Atma-Sphere posted by SamWalters on July 25, 2006 at 15:12:29:
Sam, it's a reasonable question that you ask, but there's no comparison. Other than both being OTLs, the Atma-Sphere is a very different amplifier. There are lots of posts about this in the archives, but here is a quote from the Atma-Sphere FAQ:3. Are Atma-Sphere products Futterman OTLs?
No! Our gear employs our patented Circlotronic® design which is simpler and superior in every way to the Futterman. The problems of the Futterman design are side stepped by this new approach, making OTL technology available for the first time to a much wider audience.
While some may argue Atma-Sphere's comments about "problems of the Futterman design" no one will contest that the Atma-Sphere amps are some of the most reliable, bullet-proof, amps made. And they are superb sonically. (And, there is a current manufacturer supporting the product.)
