From my current collection, these are some of the best and most versatile options (in my opinion):Just these small ones in the video. But that does beg the question that brings up another category: which sounds "biggest".
I haven't tried nearly as many small amps as you but the Mini Rectifier / Recto-Verb 25 is the best small amp I've ever played.No. I can't really pick favorites because all my amps are great for various things. These are just some picks of amps that tick a lot of boxes.
