Former Ayon Spirit owner. It’s been some time, so I cannot advise on specific tubes to roll other than saying that doing so will be worthwhile.
First, get the speaker. Evaluate it with the stock Ayon Spirit III and only then start with tube rolling.
In terms of speaker recommendation, consider Tekton Design. I’d look strongly at their Perfect SET speaker, for starters ($1,800 delivered). Your music genres and overall sound performance preferences (depending) might change my recommendation towards another model in their line up.
You’ve got a great amp. I’m sure you will be very happy once you choose the right speaker to pair it with.
