Searching through the "audiophile" websites looking for a DIY tube amp kit to build. We all know the audiophile types find all sorts of bizarre stuff to spend money on. check this out: http://www.audioexcellenceaz.com/audiodharma_cable_cooker.htm This device "breaks-in" your cables so they work better. Even if this actually worked, wouldn't it make more sense to just plug your new cable into an old HP200 oscillator? The product claims that it works by putting some extra high level signals down the cable; the old HP units put out more juice than a small generator. And they cost $85 at garage sales, not $650!
