what speakers demand high end electronics

Even mid-fi speakers could reveal the flaws of an amp, and the other electronics driving it.

I shop for a speaker that I like the sound of first. All speakers have coloration's that make them all sound quite different from each other. This includes speakers that may look similar as far as measurements go. When I have a good/great speaker that I'm happy with, then I start looking for the electronics that will satisfy me, and get along with those speakers. I used the electronics I had on hand with those speakers I chose. Being in this hobby for decades, buying my speaker of choice first always seemed to work for me. I found that this method works best for me.

I think like someone mentioned above, Alan Shaw says that so he doesn't loose sales to other companies also. I don't blame him either. Those people may buy another brand, because someone selling XYZ brand says you could use mid-fi gear with their XYZ brands. Years back, I used a receiver to power more expensive speakers I liked in the 70s,until I could afford the better separates they deserved. Harbeth speakers do show the flaws in the rest of the system. They at times will show mid-range flaws that a lot of speakers don't reveal. There are cheap speakers that do reveal the flaws of gear that are way higher than their price category. It all amounts to in the end to have a system with everything good enough and getting along while not being any standout flawed sounding pieces in the chain.
