Non shielded interconnects for connecting to tube integrated gear

I read somewhere while reading about tube integrated amps that non-shielded interconnects should be used in lieu of shielded interconnects.

Out of context, this statement makes no sense. Non-shielded cables can sound great as long they avoid nearby EMF/RFI. In other words, behind your equipment rack, they cannot run across/near any power cabling or power supplies inside components. Otherwise, noise will be introduced to the signal. Most IC’s are shielded because of the rat’s nest of cabling behind a rack.

It depends on the system setup and local room environment and susceptibility to interference/noise. Potentially unshielded cables can sound very open and transparent.  I'm  able to use unshielded cables in my  tubed system and they're terrific sounding.  This will be totally dependent on individual system variables

Depends on the entire circuit! The output impedance of the pre and input impedance of the amp, as well as the remaining reactance of the cable without the shielding. Krell’s CAST is a design specifically designed to eliminate such issues by using overwhelmingly high output impedances that this type of effect should vanish.

However my suspicion is very little.

There are some proponents of "naked" interconnects, and I keep meaning to try making my own. These are solid-core with cotton insulators and nothing else.

I have not heard or measured either. I’m just explaining the possible theory. :)
