Seeking listening help in Austin area

I live in Austin and have built an amplifier that I designed for magneto-static loudspeakers, specifically Magnepans.

I am looking for listeners to critique the sound of the amp. It is physically it is built on a wood board and is meant for 'first-ear' listening evaluation and learning only, it will not survive shipping so I have to hand deliver it and pick it up, thus Austin and the immediate area.

If you have a basic Maggie system the you know well I would like to bring the amp over and have you change it out with your amp, you listen, and tell me what you think it did to the system. This is how I learn to improve a design.

The is a Concept Amplifier, to my knowledge there is nothing like it. Class-A, no feedback, current mode gain, very high bandwidth and most uniquely, the distortion does not change with frequency and that is uses over 700 transistors to accomplish 50 watts per channel.  Results so far have been exceptional and I want to learn more. 

If you would be interested in listening and telling me what you hear, I would be glad to bring it over to audition.

Thank you,

Do you know the guys at the Sound Gallery in Austin? They are dealers of used equipment, mostly older dynamic speakers, but they have tech chops and are pretty cool~ I can't really help you b/c I'm running a pair of vintage Quad electrostats and very high efficiency horns. Those Sound Gallery guys might play, though- give 'em a call. The one fellow's name is....wait for it....

good luck,

Thank you Gentlemen for the information but my request was and is -

Looking for some one in the HOT area with a stable listening system based on or including a pair of planar speakers, either electroscopic or mangetostatic operation, and knows the sound of the system, to put my concept amp design prototype in the system and tell me what changes are heard,

Too bad my Sound Lab full electrostatics need more power. 86db on a good day. Good luck Barry, it's gonna be tough. If you just want to borrow my ears, I am happy to come listen to them anywhere around Austin. Cheers,
Spencer

What in the Hell is "electroscopic" and "mangetostatic" operation?!

"What in the Hell is "electroscopic" and "mangetostatic" operation?!"

Insight that Barry is more of an amp guy than a speaker guy.

"Class-A, no feedback, current mode gain, very high bandwidth and most uniquely, the distortion does not change with frequency"

It sounds to me like Barry is solving problems that really matter to the ears, even if they don’t necessarily result in the most impressive traditional specs.

I’m a speaker guy, not an amp guy
