Isolation base
"Wow, I just removed the Isolation base. I don't want to do that again." Barry, US Dealer
The World is Changing
Digital audio is all about timing. The further we press the limits of clock precision the better sonic results we experience. But with all that precision comes a real vulnerability to noise.
At the same time as we are pushing the limits of DAC precision, our homes are being cluttered with incredibly noisy items, from LED lighting, to multiple WiFi devices. At the risk of dating myself, I remember one year about 20 years ago when all the buzz at CES was a digital table clock that was supposed to improve the wall power. If you plugged it in any outlet in your listening room it dramatically changed the sound of your system. The promoters of this clock claimed an improvement, but detailed listening showed it to be a total loss of detail. That was our first exposure to high-frequency electrically induced noise in our systems. It was a novelty then. It is a fact of life today.
The noise radiating from a single 5 W LED light is shown here. A house lit with LED lighting could not only play havoc with all the systems in the house but effect the house next door as well. Add to this all the WiFi and Blue Tooth devices and the air is just full of high frequency noise.
Even the normal precautions in audio product design no longer suffice. More drastic measures are needed, this problem is getting worse, not better. As we travel from place to place we have tried may power conditioners, transformers, inductors and filters. The result is ALWAYS mixed. What works one place does not work best in another place. Not an easy problem to solve.
