Hi Kenster,
I probably should have asked you what resonances you're trying to drain from the PC.....
By deduction I know you're talking about mechanical resonance, and there are three sources I can think of: from the wall into the cord, from the connected gear into the cord, and from the air into the cord. Are these the vibrations you're trying to soak out of the cord?
One thing you wrote which is not correct is that something massive (and very rigid) will not transmit vibrations. The opposite is actually true. Regardless of mass, rigid materials transmit vibration very effciently. Only compliant materials are poor transmitters of vibration.
So, in your setup you have in essence greatly increased the mass of the cord by coupling it to the concrete floor. In doing so, however, you have also created a fourth path for vibration to *enter* the cord. This means that unless your speakers are effectively decoupled from the floor, you now have a very efficient path for mechnical vibration from your speakers to enter the cord.
Have you tried placing dense, compliant materials between the cord and the screws? Something like thick, soft rubber? This would give the cord the support it needs and would help dissipate virbation between the cord and the floor (regardless of the direction of travel).
I'm definitely not trying to say that you're not getting any benefits from your arrangement, but I am saying that if the benefit is there, it's not because any drain has been created - it's more likely that you've affected any resonances in the cord in a way that improves performance: shorter lengths of unsupported cable would equate to higher resonant frequencies with lower magnitude than longer stretches of unsupported cable.
I would run some experiments myself, but my room/system do not lend themselves to such a setup. I would also question whether my system is resolving enough to hear such tweaks as I've tried some other AC tweaks that seem to work for a lot of people yet make no apparent difference to my system (the Auricap tweak being one in particular).
