I purchased a new Ayon Spirit III a handful of years ago, it arrived with a remote that only worked intermittently. I opened a case with support, didn’t get an acceptable answer and returned it as a result.
As compared with other tube amps I’ve owned, I preferred products by Rogers High Fidelity (US Made and local to me) and Air Tight (Japanese made and the finest amp I've owned).
If I recall correctly, the Spirit was designed in Europe and manufactured in China.
