Cable isolators ???

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 .

Hi
I live in Peru and I thought that was way off to buy the real ceramic ones "cable isolators" and bring them here. They are way heavy. So I started to look for a local replacement. I crashed into a local electronic industrial supply store, the ones that sell equipment to the companies that supply power.
And I found almost the same ones, ceramic, (the size was like the big of the real cable isolators) 98% same look, very nice finish in dark brown, and they are designed to work isolating a lot more than you need. The Brand is Gamma. I bought each at $3.5(at that price I took 12
I tested them in my house and then with my local audio seller isolating the ICs and the speaker cable and the results were not so dramatic but real. The high extension was cleaner and the bass was more tight, also the background noise was reduced.
So, I think, if I could found this in Peru, there is no doubt you will find them in USA and maybe cheaper. Any doubts contact me at my email.
Good Luck
