Thought on OTL tube amps


Just curious....how do these sound/perform compared to tube amps with transformers? Why do you prefer one or the other? Any particular brands of OTL amps you would recommend listening to? You can see my system on my tag here...listen mostly to rock and roll with a smattering of jazz and a bit of classical once in a while. The next stop on my amplifier adventure is an OTL model, and I have no intention of trading it for either SET I currently have, as I'm very happy with both. One of the ways I enjoy experimenting with different "sound" is by switching up the amps. Just trying to solicit some opinions, of which I know there are many strong ones here at A-Gon. Thanks in advance!

As a user of OTL's for over 20 years, and now an Atma dealer, I might add that anyone who has heard Atma-sphere amps over the years, should try and here Ralph's latest designs.

As fantastic, detailed, quick and lifelike as they always were, they have simply reached a new plateau with the latest versions.

I just recently added dampers to the output tubes ( I have had dampers on the input tubes for years) I was surprised at the improvement yet again.

I am currently using the Zero autoformer with 4 ohm speakers.

Great tube OTL amps I think are they way off the audio merry go round.

Yes they need to be paired with appropriate speakers (the Zero increases the lot of compatible speakers) but once the amps are chosen, one may now look elsewhere in the system to make improvements, confident that the amps are making much of the potential in the signal.

Totally agree, provided its high quality amp
I just had my Atma-sphere MA1's updated to the latest 3.1 version (from 2.2) plus all options available have been added.

I have got to share that the current upgrades are a revelation for this amp. Wow does this amp now sing. So rich and glorious with state of the art transparency. The stage depth is jaw dropping and the images so 3D and real.

This is my first OTL amp or amp from Atma-sphere and I am taken back now realizing what I have been missing. This latest generation simply outclasses the 2.2 by a wide margin.

Yes, I am pleased to say the least. I have owned many a tube amp and this one has all of that wonderful warmth, bloom and weight combined with SET-like intimacy.
My feeling too in upgrading to M60 3.1. The M60s replaced my beloved CAT JL2s which is a great amp, but with my speakers, which are very easy to drive, I prefered the Atma-sphere - my thought being that OTLs by Atma-sphere and Joule are pretty tough to beat with the right speakers.
