Hi everyone, I’ll probably also post a comment under the next Zeos video about this since I want to let him know that QES Labs seems to had cease activity after his owner (Valerio Riccelli) might be passed away.
I think QES Labs was a very small business with Valerio doing the job of a hundred men.
I discovered this today browsing an Italian forum (I’m Italian) and a user reported this sad news.
So now Zeos’ amp might be a unique piece of equipment handcrafted by a now-deceased Italian artisan.
I hope to be contradicted.
