Horning owners what amps have you used?


Just curious what amps other owners, or previous owners, of the Aristoteles, Eufrodite, Agathon or Perikles have used. Chime in even if you don't own these speakers but have an opinion.

I know most everyone has heard these speakers with the TRON Discovery or Telstar at RMAF and the 211 is heavenly IMO, but way out of my price range.

I have the Aristoteles Zigma and a Thoress 300B SET (8w). I love it, but like anyone else who is possessed with sound addiction, as Neil says: rust never sleeps.

Has anyone used anything less than 8 watts? Or more power like a 300B PP or 845? I do have a Berning ZH270, and unlike a fellow Audiogon-er who had the ZH230 and Eufrodite and thought highly of the match, the ZH270 sound is not my thing.

I've not heard them together in some time, but our customer's comments regarding the M-60 and Horning fly right in the face of Trelja's comments. We've had customers run the combination for years. The speaker *does* like a bit of power.
Trelja, what would there be about a rear horn-loaded speaker that would make it unsuitable for an OTL??

I can't think of anything... and they've worked fine every time I've tried them.

I can think of plenty of things that can cause a particular amp to not work with a particular speaker, but I have found examples of every kind of speaker technology that works with OTLs. I would think something like this:

or raw impedance to be a far more likely explanation for a specific mismatch.
Hi Joe, I understand your empirical position as being real, but I would not regard it as universal by any means with regards to OTLs and rear-loaded horns. It simply means that the amp you used sounded the way it did with that speaker, and it does not follow that that is true of all OTLs on the same speaker.

IOW it may be that your experience was real, but that it may well have been possible to make that OTL work better by playing with other variables- speaker cables and power cords come to mind- OTLs usually don't like long speaker cables and can be quite sensitive to cable design! BTW most OTLs other than ours use a lot of loop feedback, which can cause them to sound thin on a speaker that is built with low or zero feedback speakers in mind. see http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php for more information.
