Update for all:
The Faraday cage has been sidestepped.
I conquered the severe RFI by doing a number of things. The biggest impact was changing to a balanced junction box on my VPI TNT6-HR, allowing me to go XLR right from the tonearm output to the balanced phono stage input of my Atma-Sphere MP-3. The drop in RFI was immediate and undeniable.
Other steps that helped include placing ferrite rings on interconnects, moving the whole system away from the window facing the radio tower, shorting plugs in unused inputs(but never outputs!), moving to balanced cables from preamp to power amps.
Thanks to all for your advice. Hopefully, I won't ever need to build the Faraday cage. I had copper mesh all picked out and was ready to go. Glad I didn't do it. Cheers,
Spencer
