Speaker Cables

I also agree pcocc is the best wire for audio because it has no Crystal barriers in it like ofc wire does. Ofc wire has 600 Crystal barriers per foot which is little fractures in The wire. Pcocc has zero. Acoustic Zen prices are very reasonable compared to other sellers of single crystal wire. And also ask him to use Furutech locking rcas plugs because the center pin is also single Crystal. My whole system is wired with OCC single Crystal and every time I put in a new OCC single crystal wire you could hear how much better it was.

I would go with Canare 4S11 cable.  I rewired both my systems with it in January 2020 and still loving it 1+ years later.  

Best cable I know of, regardless of cost, are the Silversmith Fidelium. And Fidelium bi wire. ($1200 8’ $275 bi wire “jumper”) Check out the reviews. They are not the usual “highly recommended”. They all come out and say exactly what I say.
Jeff at Silversmith tells me that he auditioned them in a million dollar system and they significantly better the existing cables. One reviewer bettered what he was using in his $600K system.
And the jumper is unique in that it connects both sets of terminals and has a binding post in the middle connecting to both sets.
They have a 30 day return policy.

Your thoughts on the Canare piqued my interest. I noticed that your office setup uses JBL L100 and I have the 4319, which are a close cousin.

I get all the bass I need from them and would like to know if you got the sub after going with the Canare SCs or if you had it all along. That, and the fact that you've kept your ICs and PCs (which weren't cheap) tells me that expense wasn't a consideration. 

And, if I may ask, are the highs detailed, airy and as balanced as the rest of the spectrum? As you can see, I'm being somewhat of a glutton of food for thought before I start swapping things out.

All the best,

I use a pair of Inakustik LS-2404 biwires with my ProAc D48R and love the results.
