To me the very best is Double conversation UPS. I have made that abundantly clear.
Perhaps some one can add this aspect to the list of audiophile sins:
- generating his own mains because normal mains distributed by electrical companies is not good enough for his audio system.
Although I agree with you this is a definitive and good solution, it is a defeat of engineering accepting that an audio system does not have rejection enough of mains induced noise and distortions, and needs a separate generator.
BTW, it was stated clearly before that power line mains grounding to Mother Earth only affects safety and does not have any effect in providing a good out path to noise. The magical effects of grounding to earth in noise are just an audiophile myth.
