If you are in to buying expensive cables I won’t be able to dissuade you.
I won’t try.
But as one of the few JA Perspective owners I’ll mention my own experience, as a data point you might consider: My Joseph Perspectives are in a separate room from my amps. I run standard pro-grade speaker cabling - in this case a 40 foot run of Belden 10awg cable (5T00UP on the Blue Jeans Cable site) from my CJ amps to my Perspectives.
I heard the Perspectives plenty of time at my dealers, with all my usual test tracks, where they were hooked up to very expensive speaker cables. There is no discernible loss of sonic information in my Perspectives at home using the regular pro grade cable. In fact, my Perspectives sound "better" at home than in the store (set up/listening positions etc optimized in my home).
Likewise, I’d owned other high end speakers, one pair of which I sold to an audio reviewer friend. At my friend’s place I would listen to the same speakers hooked up to $50,000 worth of cabling - top end Nordost, Crystal cable, others - and, no, I wasn’t hearing things I didn’t hear at home with those same speakers hooked up to the Belden cables (and my inexpensive interconnects in the rest of my system).
I know well the pull of "wanting to make sure I’m getting the most out of my system" and if one is inclined to believe cables make big differences...well...there’s a market for that :-)
If you are gonna spend a lot of money on cabling: Jeff Joseph is well known to be fond of Cardas Cables. I believe he almost always shows his speakers with Cardas
