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,

@geoffkait , It looks like I misunderstood what you meant by "twice the volume".  

It can mean "subjectively twice as loud", which is generally considered to be +10 dB.   That's now I'd normally use the term.

But it can also mean "equivalent to doubling the amplifier power", which would be +3 dB, which is indeed what we'd get from sitting half as far away from a line source.

700 x probability of failure.....make mine tubes....
but what a cool experiment 
ignore anything I wrote....

@geoffkait @audiokinesis Thanks for the comments, but there's no trouble getting proper volume at normal distance in my setup. What I meant is that my speakers probably would not be a great candidate for the OP to use to test his 50w amp. 
In fact, I don't think there are many electrostatics that are a great match for a 50w amp; perhaps smaller Quads, but certainly not larger Maggies, Sound Labs, nor Analysis Audios. Barry, even if your amp sounds inherently terrific, it will mate well with a pretty darn narrow slice of the speakers in the market IMHO. Bridgeable monos? A bigger brother? Cheers,
