Did anyone for a minute think that audio interconnect cables might not test different at radio frequencies?

While balanced interconnect systems are always good. An all balanced internal circuit is an engineering challenge and seldom beneficial .

Trying to measure cable differences with a microphone is just wheel spinning.

I would suspect a high or low AC line voltage problem. With a little "Kill-a-Watt" meter (or similar) check line voltage in several rooms. And again when hig powered appliances or HVAC are operating.

I missed that. So he needs a speaker level to line level reducer. Radio Shack had one in the automobile sound section (but that was then).

Why not just "Y" Wye to controlled output?

I was at a test equipment mfg. local office open-house and they said that they used a dish washer when repairing old equipment.

A microphone cable is a sub-set of balanced XLR interconnect cables. It is optimized for flexibility, robust construction and low handling noise. Any microphone cable can be used as a analog interconnect cable, but the opposite is not true.

Just the opposite! It's not a shield, and would mess-up the symmetry of the TWO central conductors. Just get a Shielded Twisted Pair (STP) bulk cable from a major industrial manufacture. You can't DIY anything even close.

A reasonably priced O-scope is not the best tool for measurement. But a 50 megahertz O-scope is a great toll for troubleshooting interference, ringing and oscillating.

on the ZeroSurge 8R15W-I spec sheet, it has: 4 duplex receptacles are isolated from each other. I wonder what that means?

Not even close to symmetrical. It works with unshielded bonded pair Cat cables. But that's about it.

Just because there is continuity between two functions, does not make them the same function. XLR pin 1 is connected to the chassis. The circuit common and DC supply common are also connected to the chassis. a] in an XLR balanced interconnect system, the shield is not always connected at the...

There is no need for a StarQuad cable in a residential audio system.

There is no 'ground wire' in an XLR balanced interconnect system. And a wire would make a awful shield.

In a balanced interconnect system, there are two signal conductors and a shield. There is no ground wire! In a balanced microphone system, there are two signal conductors and a shield. The shield is often part of the phantom supply and may be at the phantom supply common potential. It is...

I just noticed that NEC 2020 & 2023 now require a whole home surge protector.

For units that have CD/DVD players, hard drives, big fans or motors, I use: Sorbothane Hemisphere Bumpers https://www.edmundoptics.com/p/hemisphere-foot-package-of-4-sorbothane-bumpers/4139/ Because sometimes the shelf acts as a sounding board.

Hard to schedule, but what about a neighborhood power outage. At home I sometimes hear what sounds like a pump or compressor.

In the US, Redco and Markertek are excellent providers of cables and pro audio equipment. https://www.redco.com/ https://www.markertek.com/
