Does hybrid amp really has the best of both world?

It's either best, worst or in the middle of both worlds, but both worlds for sure.

Not to mention you need to lay out a C-note or ten for a good tube tester unless you get off switching 8 tubes in and out to find the hiss a couple times a month.
SS has improved enough in the last decade or so that IMO tubes, though I still have a tube amp and 3 tube preamps, are a thing of the past.

So true, Czarivey

Schubert,

SS or tube or hybrid continue to progress. I don't think any of their engineers stop making improvements.

Yes, also we really need to support Putin's efforts by buying
Russian tubes.
