Why are Ayon tube amps not mentioned very often?

Truthfully, I feel it has something to do with their methods of distribution. A little too much exclusivity!  I believe that at the minimum, they should be represented by distributors located in at least 3 regions and cities that are accessible to audio enthusiasts, to be able to audition, in concert with a few exceptional loudspeaker products. AYON, under a different marketing name, also produces an exceptional line of loudspeakers that have almost no representation in the US.  In my opinion, AYON has developed some of the most musically sophisticated. electronics offered in the world market today. PRICEY;  - -  YES!  Yet, when compared to their competition, no more so that other electronics that actually don't offer as much true audible satisfaction for the dollar spent. Their CD players are also amazing. To the point where they have little or no competition. AYON also need to do a better job of representing their products at the big audio shows. For so many people, the audio shows nation wide, are the only place where people can get up close and personal with AYON and some other fine audio products, not readily available at dealers.

I've owned Ayon Triton II Integrated + Dynaudio C1 for 4 years and I just listen to it and do not mention anywhere :)
Really great sound which I do not have any desire to move from. Bought used as would not justify the price of a new one.

I bought a used Ayon Spirit III a year and a half ago, and I love it.  Best amp I've ever had by a mile.

Ayon makes great sounding components but as you climb up in their lineup, they get quite pricey.
