Not knowingly anyway. I'm not a regular of these shows and mostly I was interested in hearing the various listening rooms just so that I could get a sense of where my own system is in the pecking order. We didn't go to the upper floors and I don't recall being in a Krell listening room.
It was cool to see/hear Wilson's first set of speakers.
I'd post a full review of AXPONA but I'm not qualified. It looked like attendance was good and people were happy to get out.
I was looking to see if there might be some Tekton products there as I was curious about them, given all the talk on this forum, but I didn't find any. Seems like a missed opportunity for a company that doesn't sell through dealers so impossible to hear them without buying.
