A shade tree improvement.

My first switching amplifier a PS Audio HCA-2, before I rewired my early seventies California home could be heard on the bedside Sony clock radio.

I constructed a DIY 10 gauge positive and common with an 8 gauge ground. I wrapped the cable with copper foil tape followed by a braided tube wrap grounded at the male plug end. This dramatically improved the RF issue. There was an immediate sonic difference akin to replacing lamp cord with a decent speaker cable. This amplifier took so long to run in detailing these sonic benefits continued to change for sone time.

After the homes amperage increase and the rewiring which included uninterrupted dedicated 20 amp BX clad lines terminated with metal receptacle boxes. Essentially shielded power from the underground grid to the components. This work was by far the biggest improvement in not only the audio and HT but seemingly everything electric.

I eventually replaced the Cardas Golden Ref speaker cable with some NuForce which offered slighly more body and definition.
