what speakers demand high end electronics

ALL speakers require high end electronics to sound their best. All sources require high end preamps to sound their best. All amps require high end speakers to sound their best. All anything requires all high end everything else to sound their best.

I can't believe I just took the time to write that. That is the end of this thread. There can't possibly be any other answer.

Sorry Herman, I have to add one more thought. To sound their best, all speakers need to be fed by well matched components. A system put together with a bunch of high end mismatched equipment will not make MUSIC.

The question stems from Harbeth speaker designer Alan Shaw's statements that his speakers can do just fine with inexpensive amps. I know there are speakers out there that owners say would be need very fine electronics to make them work. So thanks for highjacking my little bit of entertainment with my hobbie.
