@jea48 I read that… sounded good but wasn’t sure what it meant. I assume based upon your reaction, that is good. 😃
AC Power
I have a relatively nice system, but have done nothing with my AC power, with the exception of upgraded PC’s and a cheap iFi plug in power conditioner. My question is multi fold… do I need to do something, and if so what? Dedicated line (15A or 20?)? Quality power conditioner? Both? Which one first? How do you tell?
My system is a combination of HT & 2 channel & I tend to use both simultaneously as I like to watch sports while listening to music.
My amp is (I think) a relatively low draw… Moon 330A, Rythmik sub, BHK pre, Aurender, Qutest w/Sbooster, R11’s. No high power amps are in my future & never listen above 75db. I do currently plug my amp directly into the wall. All my wall warts are gone. For my HT, add a 75” Sony TV, Marantz 7015 AVR & a Klipsch sub (although at zero volume the AVR & sub should not come into play).
I am considering buying the Furman IT-Reference 15i or 20i first as they are well reviewed & are priced very well on Amazon ($1,400 / $1,900). Before I pull the trigger, should I go dedicated power & at what amperage (my nephew, an EE & audiophile thinks I am drawing no more than 5 amps) as that will dictate the Furman model?
Interesting, my nephew thinks neither are worth the investment. His statement: “Do you have appliances on the circuit now? What kind of interference can they inject?...voltage drops would come from current draws...which trip breakers.
Not steady 60hz a good power supply handles. So it all comes back to was the power supply engineer dropped on his head as a child.”
”Personally I think it’s something audio people do when they have run out of gear to buy.”
Any thoughts or recommendations would be appreciated. Thanks!

I consider @erik_squires the Audiogon resident expert on Furman power conditioners. He has more knowledge than I on Furman power condioners technologically. @erik_squires is better qualified than I to answer your question regarding the design and circuitry of voltage regulation of the P-2400.
As for me the way the P-2400 voltage regulation, design, circuitry, is implemented sounds pretty sophisticated to me. Switching from a winding tap to another winding tap without causing a distortion in the sine wave or any type, no mater how fast, the switching method used is not an easy thing to do. Furmam seems to have it figured out without the user hearing anything from his audio system. If not you would be reading about it on the Net.

@jea48 - The approach Furman takes, which appears to be to switch as close to the zero Volt crossing of the AC waveform is pretty thoughtful and not common among all regulators out there. IMHO it’s a very cost effective design overall. Interestingly enough, Roger Sander’s Magtech amps take on a similar approach, offering rock solid power rails to an overbuilt output stage made by Coda. In that case however, while he does switch taps at 0V, instead of using an autoformer he switches taps on the main power supply transformer, which of course is quite custom. |
@carlsbad2 That’s twice you have been an a.. on my forum. |
