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. Is this just snake oil talk or is there any scientific rationale for doing this?

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. :)

Clearly I was too busy driving to write correctly. :) I meant to say:

"Shielding adds a tiny bit of capacitance in exchange for reducing the chances of EMI/RFI noise."

It's not entirely snake oil, but it's not necessarily just for tubes, and not necessarily better. 

Shielding adds a tiny bit of capacitance to the cable at the risk of extra EM/RFI noise. If you can get away without the shielding it might be better.

In this case, your mileage WILL vary. Enjoy experimenting.
