Started out with Richard Gray Power Products to PS Audio regenerators,
None of these things improved my listening pleasure in my 2 channel audio presentation. I wasted tremendous amounts of money on these things. Guess I paid for my stupidities.
For instance, do you know that some regenerators carry varistors in front of the high current outlets.
And don’t fool yourself, dedicated lines do not remove anything from the power lines, they may help to lower the impedance, but by how much at what price tag.
Even though, as I said, if you find an improvement, I can tell you it is not a bang for the buck.
The other thing, is most big-name manufacturer spends a large part of their on budget tank built structure, instead of implementing superior musical designs, and, not to mention the cheapest electronic parts like transformers, capacitor, resistors etc. that they fit in their products, you can buy better parts even at Radio Shack
