71.198.165.130
some say that equipment made for 120 and more important than even 120 v9olts is STEADY CURRENT. NO FLUCTUATION OR HEAR IT. .....
others say that all devices that reconstruct the voltage likE PUREPOWER or even ACCUPHASE...affect the dynamics IF YOU HAVE SENSITIVE SPEAKERS LIKE HORNS -- U CAN HEAR IT.others say that as long as above 116 volts -120 u fine. no hurt equipment, and better off not using any reconstruction device.
sure would like some EXPERIENCED opinions of those who done it with and without accuphase etc..... i would thank u for that.

Hello there:Interesting question, indeed. As we all know, Power is probably the most crucial component in the final sound quality we get "The better the power in, the better the sound out".
Conscious of that, a few years ago I decided to work in the Power Area of my System, running a Dedicated Circuit and Dedicated 240 Volts Power Line plus the Richard Gray Power Company 240 Volts Sub Station (I already had the RGPC 1200s Power Line Conditioner with which the 240 Volts Sub Station works in tandem) . The improvement on my final quality sound was devastating, beyond my highest expectation. That 240 Sub Station is a Step Down Transformer (to 120 watts, very stable).
Here some excerpts form the manufacturer's website:
"The 240 Volts Sub Station is a huge Isolation Step Down Transformer utilizing 240 Volts Line for total Isolation of the AC circuit. It provides max lightning protection, no ground loops and nearly 1000 watts more than a 15 amp. It is a true monster of 2.5 Kilowatt Isolation Transformer. It provides a truly Balance Power to any System. Using the RGPC 240 Volts Sub Station is the closest to plugging any System to the Street Power Pole.
It prevents the ground loops that creats hums in our sound and degrades our picture quality; it completely isolates the AC line of the System from the rest of Power grid surrounding it, bypassing all the power fluctuations from the rest of the house.
It is designed to convert the true 240 volts into an isolated 120 watts with 4 Commercial grade, 20 amp Hubbell AC outlets that provides twice the amount of power over a standard 100 volts outlet. Additional benefits include surge protection and A/V system that runs more smoothly and consequently generates less heat, which helps extend the life of the components.
So my answer is an emphatic "Yes, a stable power makes a real difference and it is audible in your final quality sound".
soundquest,I too have the ubiquitous PS Audio P500 - your system is more than transparent enough to differentiate preset voltage variation. Living in the UK, voltage is 240 and I hear the difference in voltage swings from 220 thru' 250v.
I run my source components at 220v - the sound is apppreciably slower, less dynamic/duller and softer at the top end and generally more relaxed - may be totally imagined... but FWIW, that's what I think I hear on A/B and I also feel assured that a 10% drop in operating voltage is less stressful on my vintage components and valves and I guess, I'm doing my Kiyoto consciousness bit (if only in spirit) before the raging tiger bites our fat decadent backside, as it surely will...
Enjoy
