Electrical skin effect says that the coax would perform similar to solid silver cable. The 98% shield rating would say that it would keep your sensitive input signals well shielded.
Matter of fact, I'm gonna use it for my TDA7294 BTL input cabling.

I've got some Mil-Spec Plenum RG142, 100% braided shield and solid center conductor. Both are silver over copper. Would this stuff make good interconnects?
Yes. I picked some up cheap at surplus and used it for interconnect wire in both my hifi rig and in my lab. No particular issues other than it was a bit stiffer than I'd like.
Coax cable is very nice. If you run them over very long distances just make sure your preamp can "drive" the somewhat higher capacitance.
I'm using RG316/U and I like it.
Oh, and wow, this thread is old.

Maybe a little? American Wire Gauge table and AWG Electrical Current Load Limits with skin depth frequenciesSkin effect at audio frequencies? No

To my knowledge the skin effect is an electrical property that even occurs at 50-60 hz (Mains Power Frequency). It would seem to me that skin effect does play a role, now, when you are talking the lengths needed for intracabling of an amplifier though there will be immeasurable losses. You should only gain a quieter input source from the 98% shielding.

Wow talk about resurrecting a dead thread. I think this is a record for one of my posts; almost 7 years.
Anyway, I too found it to be to stiff for my liking. I have had much better results from RG-316 and RG-174.
In any case skin-effect at 60 Hz only matters if you are the power company delivering huge amounts of current through wires who's diameter is measured in inches.
Or very high frequency PCB's where due to skin depth AC resistance varies with frequency, but were way above the audio band.
At audio frequencies it will behave more like a screened piece of wire than a coaxial transmission line. It might not even have a well-defined characteristic impedance over the audio band, but fortunately unless it is a few miles long this won't matter.
