I’ve been in this hobby since the early 80’s and had not heard of them, but I am not much into tubes other than for preamps and guitar amps. They just don’t have that low end power that I enjoy, not to mention the inconvenience of the maintenance. I looked at the AYON website and they seem pretty nice though. Maybe I’m alone in not being familiar with the brand, but personally, I’d go with a more well-known brand whose sound signature/ voicing I was familiar with, unless they offer at least a 30-day in-home trials with a no questions asked refund policy. Just my thoughts...
