PS Audio Regenerator versus Balanced Power/Isolation Transformer for Phono Stage?

[Rumpole]

Rumpole, I see you’re in Colorado. If this readout is correct, then it seems for part of the day your AC voltage is riding above the 126 VAC limit which is defined as maximum (+5%), and apart from that you seem to be otherwise running at 125 VAC, which is certainly at the upper limit of the acceptable range. Not sure if using a regenerator to provide a stable 120 VAC will help, but it’d be interesting to hear your results if you tried it. You might want to call your provider to see if they can check your incoming voltage and confirm that they see it exceeding 126V.

Hi Tony - Thanks, and the Whisker/Ting report also says that the "Acceptable Range: 108 to 132 Volts", although maybe this is not ideal for audio? I have solar panels and suspect that they might be causing the high voltage in the daytime.

@Rumpole That Quiescent is quite dear.

If you're looking for a perfect sine wave for digital, Isotek Genesis is the way to go for digital.

It's quiet and works wonders for digital.

You can't use it for amps though, like PS audio.

I only use it for a streamer or DAC.

The U.S. national standards specify an acceptable range of 120 VAC +/- 5%.

The Torus I used was the one with 45amp, not wall type and came with many outlets, I dont recall the model.
Back then I had similar system to GTT audio namely double monos Audionet, Kronos, Audionet and Soulution electronics, big YG Sonja. I hooked everything to the Torus. The power was much more than adequate and therefore excellent dynamic. The sound is on the warm side. This thing guaranteed me super stability in power and gave me excellent protection in surge and drop in current.

The drawbacks were the lack of "Life." You wont realize it until you have something better that all the sudden make sound a lot more open, no veil, more transparent and better highs. So, not that it was not good but I found just better alternatives.

If I may second your thought of using a power conditioner, some of the most respected systems here in WBF dont even use the power con at all. I do believe that clean power is the very essence to ultimate sound but all power cons that I had in my system had their way of adding or substracting too much to my liking.

Kind regards,
Tang

Unfortunately I haven’t come across any transformer power conditioner that doesn’t kill dynamics and life. A transformer based power conditioner is totally different in design to a stromtank but equally bad in sucking the life out. I never want a transformer or a battery powered one channel transistor based amplifier feeding AC to my setup.

I agree you , with my TAD Reference System I use no ac filter I use no isolation transformer I use no high capacitance AC cable I use no dc blocker I use no emi filter I use no parallel filter I use no AC regenerator .

I had all of them but never liked them. I also had swiss made 20KVA UPS from ABB company but it was not good. Power and dynamics were ok but the harmonics were off.

I asked TAD Labs to design a transformerless class D 30KVA AC regenerator.

For low power systems like 10w tube amplification I use Purepower 3000+
