Lead shielding

I have made myself a cable tidy which effectively boxes my loudspeaker cables from my 2 aerial cables, and a phono lead from my TV to my amp. The makeup of my room makes this unavoidable.

I designed it with a view to shielding the TV based cables and running a grounding wire to a rod in the garden. I considered the following:
1. run the cables via copper pipes - grounding the said pipe
2. line the respective 'box'/'run' with lead - ground that.

I thought about lead because I saw a roll in my workshop, and understood it to be an effecive shield

Loh, do you hear any difference with or without the shielding?

Lead seems like a reasonable material to try.

I use Mu metal to shield my noise sensitive low level phono gear, works well. It was designed specifically for this purpose in other applications. I think Mu-Metal uses Nickel and Iron mostly, not LEad.

I have read published data on the internet about measured shielding effectiveness of various materials. A google search might be informative.
