Shielded cable between pre and SET amp


I have been using Duelund ICs for a few years and I love them but with my new SET amp, there’s a hum if I don’t use a shielded cable. Any suggestions for a good Duelund-sounding shielded cable?

Thanks! All great suggestions. Amp definitely not the source. I wasn't aware anyone made a shielded Duelund cable, but I may try to add a shield first just for the fun of the attempt.

Ok, update. The problem was the SUT that was sitting 2 feet from the preamp. Figured that was enough. Moved it 4 feet away, still noisy. Using the built in SUT now. Frankly it's hard to tell a difference. Problem solved!

Problem not solved!

The external SUT sounds so much better than the internal one that I'm just going to have to get some longer cables. 

I don't think it is a proximity issue with the external SUT, when I have used external SUT in the past I have always needed a shielded cable from the SUT to the phono stage or phono input on a preamp to avoid any hum.

What's a SUT?

I run a 45 SET with ICs that happened to be shielded, and I'm the process of building unshielded IC...hopefully I'm not heading into trouble.
