What I don’t like about tubes is the high voltage supplies. If something goes badly wrong you can blow up speakers, and if you like Quad ESL's, well, you can end up a lot of KV over-voltage, leaving just about everything dead but the frame. Unless you have really good protection circuits, which aren’t really good for the sound.
So I built very clean SS amps with +/- 25VDC rails. This cannot drive my ESL’s into protection, so I was able to disconnect the protection circuit and improve clarity considerably.
Maybe there are better amps out there, but the system of amp-speaker, I suspect, is as good as anyone’s. At least, anyone who doesn’t have access to military or equivalent hardware.
