Hi Bob, I have a vintage pair of JBL L-7 speakers with the Tara Labs Omega Jumpers on them and I own Poly crystal speaker spikes and still points speaker spikes I rotate from time to time to make the speaker cabinets inert alot better than what they were designed to be, They sound wonderfull!, I am sure I can get better, But at what crazy money are we talking about?, My speakers are 4-way, cross over at 900hz, and do 30hz to 27khz, My wife is into the audio nearly as much as I am, I believe she would use the cables that we own, I am with you on that, anything could happen, I hope she does not cut up the cables If I kick the ole bucket, LOL!, have you ever done any modds to your equipment before?, I am starting to get knee deep in doing so, for the money, The performance returns are very well worth it!
