I run two different SS amps in two systems.
My main system uses Bel Canto Reference 1000m Class D monoblocks, 500w/ch, with a tube pre-amp friendly 100 kohm input impedance (unbalanced), 1000 damping factor fed from ARC sp16 tube pre-amp driving large OHM Walsh speakers that are known to benefit from high damping. THe sound is fast, vivid, powerful and articulate at ANY volume with any music. About as good as it gets I would say
ONce when the BCs were in the shop, I used my TAD 125 Hibachi monoblocks as a sub in their place. THese are 180w/ch SS and designed to provide tube like sound in a SS design. These have significantly lower damping and lower input impedance than the BCs. The sound is also quite good though not as much muscle and slightly less articulate in the bass compared to the BCs. The difference in sound corresponds exactly as I would expect from the differences in power and impedance ratings. You would likely not realize you were missing anything with the TADs unless you heard them in comparison to the BCs. THey still sounded really good, but not as good as the BCs.
I also have smaller OHM Walsh speakers in my second system. These have smaller Walsh drivers that are not as challenging for an amp to get a vice like grip on the driver for optimum control, articulation, detail, etc. They work even better with the TADs.
The TADs do have a lovely tonality in the midrange that I fancied compared to the BCs, I suppose part of their SS tube sound design.
Just an example in my case of how these kinds of specs actually turned out to be useful in choosing gear that works really well together.
