Finding a specific cable

Matthew Bond?

Got it in one!  Thank you!!!

They’re on the expensive side. 

Expensive is an understatement.  Unobtainium for me, not that I'd want them.

Crazy expensive, but hey if you can afford them good for you!

That type of cable has high capacitance. Not good for some amplifiers. You can craft similar from ordinary ribbon cable if you must have flat cables. Better performance can be obtained by using woven ribbon.

Unfortunately, I need a 40’ run for. my speaker cables or interconnects (one or the other). I’m looking for the best options.

Definitely think outside the box for EXCELLENT cables at prices so low they make people question "how good can they be?" I made the plunge buying a coax cable to compare to my Pangea Premier XL ($169). The cable I bought (free shipping/return) was about half the price. WOW. The only downside is it takes about 3 weeks to S Florida. That experience was so positive that I ordered a power cord and XLRs. The XLRs were from a well known highly reviewed cable company at ~ 10xs the price, as were the power cords, and speaker cables. This initial experience immediately led to replacing all the cables. There are several choices on Ali-E; mine are snow white. You'll figure it out

Interconnects should take up most of the distance.

Many esoteric speaker cables have LC properties that can wreak havoc with some amplifiers, especially with longer lengths. Eight feet is more than enough length for most home systems.

IF you need flat, Goertz made nice sounding ones. For reasonably cost long cables, do what the pros do: balanced Mogami long interconnects. Keep speaker cables short.

Received wisdom is that for long runs you must use balanced ICs.

Balanced only pay benefits is noisy environments. Improperly done, they can be worse that unbalanced.
