I would like 200W, but honestly that is just my dogma leaking out. I need what I need and not an erg more. How much is that? Sol's 30W integrated can play loud rap forever. Mike's RE Designs are quite stout little buggers at 75W. But both of those have well designed (nuke proof) power supplies with plenty of headroom. I guess loud orchestral passages with bass drums and their reverb are my biggest power draw. Technically 75W is enough with my easy load 90dB speakers. But headroom has a sound of its own. I am not in the 1000wpc camp, I crave extreme refinement and infinite resolution.
I already have $4500 amps, which I consider an incredible value in high power tube amps. So if there ever is another amp for me, I expect it will cost more. I have already researched and crossed out Moscode, Parasound, McIntosh, McCormack. They are refined versions of typical class AB SS. I want more for that kind of money. Spectron?, Transcendent BEAST, Pass XA 100.5, you know, something really awesome, with perfect tonal accuracy.
H-Cat concept is actively maintaining waveform velocity at several points in the circuit, which preserves tone, harmonic integrity, and of course soundstaging. The blur that messes imaging also screws up tone with the same smearing in time or space. It's like feedback without the time delay. These Usher Be tweeters and midranges are a miracle, so I want to feed my little miracles royal jelly and be utterly amazed every night. I also want to be mentally inspired by truly innovative gear as a work of art in itself. So weird stuff is always appealling, but I am also a very careful shopper.
Anyway, I am fortunate to have a local dealer with the pre and amps in stock, so I will be able to get a sense of what's all the hubbub, bub. I got my Feastrex drivers from him, nice guy. I will still need to hear them at home before any ink is shed in their name. I think there aren't very many amps built yet, < dozen maybe.
