otl vs push/pull

I think Tvad's idea is sound. I would also go to the Atma-Sphere homepage, read Ralph Karsten's white papers and some of the reviewers' impressions to give you an idea. Ralph's writings are uncontaminated by the usual hype. He is a man who can be trusted.
I myself run p/p monos and Ralph's 220 watt monos in my configuration driving the big Sound Labs. I like the sound of both, but for delicacy, air, bloom to my ears the Atmas play in a league of their own, especially in my configuration and room.

Call Ralph if you have unanswered questions. He is awesome and honest and won't oversell.

IME, OTLs provide a tremendous ability to untangle complex music in a natural way that beats anything else on orchestral music. Natural timbre is another strong point.

With Atmas, run balanced if possible. Cheers,

Spencer

Hello, You should seriously also consider looking at the NAT Audio push pull power amplifiers in addition to the OTL products (www.nataudio.com).
The model is called Generators.

While I'm partial to these components because I import them, we've had many customers that have raved about these.

Happy listening.

OTL can sound good or bad as PP amps. Matching with the right speakers is critical. The factor which keeps me from OTL is if a tube shorts and blows, the speaker may get toasted. Proper protection is a must....safe music is a must...jallen
