Cable isolators ???

I use a set of audiophile cable insulators to lift my speaker cables off the carpet. They make enough of a difference that the day I put them in, my wife came home from work while I was listening to a well-recorded CD of jazz vocals and the first thing she said when walking through the door was "Did you change the tubes today? That sounds really good." So in my system it makes a real difference.

ElDartford - interesting experiment - How were you monitoring the preamp? On an oscilliscope? Connecte to a power amp and speaker? I've always felt the same - cna't understand how vibrations affect solid state electronics, and especially cables - although I could see where proxsimity to a di-electric such as a carpet might affect the cable properties.

I use them in both my systems, and they made a readily audible difference, mainly by lowering the noise floor. Well worth the investment, IMO.

I also use cables isolators on my system, i bought them because i did not wanted to let my expensive cables on the floor.

The sonic improvement is totally non existent to my ears.

I am usually in complete agreement with much of what Mr Eldartford has to contribute . I have also learned much from his posts over the years . This time however we agree to disagree. Isolating the components from the effects of vibration is { im my system , to my ears} a critical component in high end sound reproduction . Isolating a transparent digital source can make a dramatic improvement in its performance as well as tube amps and tube preamps in my system . These improvements only became clear once my system reached a high level of transparency however. I am however speaking of a system that is in a room with suspended wood flooring .
