Regarding PS Audio not showing at Axpona, a $10k loss when the show was canceled is certainly a hit, but in the grand scheme of PS Audio's total revenue, especially when it is amortized over the two years without shows, that is not a big loss. These were also two years when their sales likely flourished due to audiophiles being stuck at home during Covid. I suspect their decision not to go to Axpona is based on principle or ego. The $10k will come back to them in the sale of a handful of power conditioners.
That said, it may be a fortuitous decision. I visited their room in Montreal several times, sitting in many positions as well as walking around the room and I think their speaker still needs work. That, or as Optimize suggested above, a lot of room treatment or DSP.
