Recommended Speaker List for Atma-Sphere OTL Amplifiers.


OK, I am not sure how many times this has been disscused but the information is found all over the forum. I would possible love to compile a list here.

I personally own the Classic Audio Loudspeakers T1.5

I am now looking to build a second room with the M60 Mono Blocks and MP-3 Pre-amp.


Would love fellow audiogon memebers posting any feedback with speakers they have used with these Amazing OTL sounding Amplifiers.

I am well aware of the smaller inconvenience of owning OTL gear but in my honest opinion for this level of quality in enjoyment I am more then willing to compromise. Once the match of the speaker and amplifier is complete all you experience is pure magical bliss!

The T1.5 Classic Audio Loudspeakers are excellent and magical theirs nothing like it. Its just flows with music in a emotional way that sparks your deepest feelings so easily, I feel like I'm transported somewhere else. 

The speakers are full field coil. These are a keeper I would never part with them. Mines are paired with the New Atma-Sphere Amplifiers "Nirvana". A Super Regulated OTL Amps LOL The best Atma has developed till date I guess.

The OTL amps have been a revelation. I was more in to SET and certain push pull class A design but never experience this form of lucid feeling from a sound system.

Its going to be hard to find a speaker that can perform like a Classic Audio Field coil but in a smaller and less expensive package and designed for smaller rooms.

I have been considering smaller horn speakers or Single wider-band drivers too. Just not settle down yet and need to go out and listen to some of the manufactures that are based in the EU.

My ultimate goal was to build a smaller system with another set of Atma-sphere gears this time with the MP-3/MA60. Once you go OTL you cant go back :-)  Everything else just sounds slower and less transparent. I cant seem to enjoy my previous gear (for second system) and thus had to sell some of them off.




Good suggestions here, thank you all.

I remember Ralph telling me he used Bud Fried's loudspeakers when he developed his amplifier, and I'm not sure there's a better match for either.  The series crossovers and true transmission line couples magically with the OTL.  Even after a couple of attempts at revival, sad to say the brand has faded into the vapor.

For what it's worth, though still owning several other speakers, including several Frieds, after hearing the Quad ESL57, which Bud brought to the USA, I've stopped thinking about loudspeakers.  No other brings as much reality
Dragon-vibe.....can you expand on your statement....I know very little about OTL

"I am well aware of the smaller inconvenience of owning OTL gear "
 @gwng8,
 I hope Ralph (atmasphere) responds. If not, you can always PM him.
I own a pair of MA-1's and have found them to be the most remarkable amps providing unmatched sonics as well as reliable, trouble free performance.
Go to his website, he has some good pages on his design.
As far as OTL inconvenience, there were earlier designs (Futterman, I believe), that were known to be problematic. Ralph's design improves upon this and makes his amps essentially bullet proof.

With my Atma-Sphere M-60 Mk 3.3 I ended up making my own DIY speakers. I stayed with 8ohm hi sensitivity drivers. The cabinets were purchased from Parts Express and are High Gloss, they look very nice.

I used Aurum Cantus G1 Ribbons and ScanSpeak drivers. My DIY external crossover boxes were made using Mundorf SGO classic caps, Path Audio resistors and Janzen inductors and the speakers were wired internally with Cerious Technologies Graphene Extreme wire.

Recently, I thought that I should upgrade my amps and then speakers. I don't know why just had the itch I guess.

So, in the last few weeks I have heard Magnapan 3.7i's with Rogue Audio amps, (very disappointing IMHO) Focal Kantra 2's with Nagra $80,000 amps and today the Goldenear Reference speakers with some $$$ French amps.

To my ears, none of these amps/speakers combinations sounded as good as my Atma-Sphere M-60 3.3 with my DIY speakers.

Bigger and more expensive is not always better...
