@testrun I did try moving to long XLRs.
At the time my system consisted of Pass Labs XP12, Pass Labs XA30.8, Lumin U1 Mini streamer, Bricasti M3. I used Acoustic Zen Absolute Copper 1m XLRs throughout and Audience AU24SX speaker cables. I moved the system to the side wall and left the amp between speakers. Ran a 15ft Mogami Gold Studio XLRs from XP12 into XA30.8 while the Bricasti was still talking to XP12 via the 1m long AZ Absolute Copper.
At first heard a bit more definition and focus without the rack in between speakers and thought I liked it. Shortly after when the initial excitement wore off, I started hearing changes on tonality that I didn’t like - added harshness, glare in the mids. This is of course in comparison to a silky smooth Acoustic Zens.
I lived with it for a month then moved it all back. It was not worth the effort at all to me.
What I did though to kind of strike a balance of clean space between speakers with components still in their space is lay it all out on the amp stands. Take a look at the attached picture
But if you want to go the long XLR route, I think BlueJeans belden XLRs are going to do the trick
Good luck!
