I fully respect you going by your own experience Mark.
In my experience, I've heard the Perspectives hooked up to various very expensive amps with wildly expensive cabling etc. Yet I thought they sounded better when I had them in my system for audition at home (I use old Conrad Johnson amps, but cheap interconnects, plain old Belden 10awg speaker cable, no after market AC cables, etc).
This is pretty consistent with many other similar experiences.
First time I heard Quad ESL 63s my mind was blown. Even though they were being powered by a saved-from-a-garbage Dynaco ST70 amp and no-name cables. The difference that I heard compared to anything I'd heard before was due to the quality and character of the speakers.
I just came back from listening to music at my friend's house. He's a reviewer. Has something like $50,000 worth of the most highly lauded interconnects, speaker cables, AC cables, $20,000 phono stages, all that kind of thing. Sounded great. But I think what I have at home sounds "better," despite my non-audiophile-approved cheaping out on cables etc. I attribute this to the importance of speaker choice, positioning/room acoustics, and then choice of amp, source....
We all have our own path :)
