Good / Bad designs of both exist. It may not be easy to compare, though since speakers won't be best electrical match for both at the same time.
Best SS designs tolerate some reactive loads better than tubes.
So, if you compare 'best-to-best', you may end up with a tube amp and a certain type of speaker...maybe a single driver, while if you audition a SS amp, you'll find a better speaker.
So, If you're thinking of using a reference pair of speakers to just go thru amps until you find the 'best', forgetit.
Comparing 'best', again, it may BE impossible to tell the difference between tubes and SS in many cases and when using synergistic components. Should that be a surprise?
