@signaforce , I sent you a PM through the Agon message system.
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!

@jea48 I received it… thanks! You should have received a couple replies. |
I am back to buying the P-2400 for all the reasons I stated earlier…+ not only spacing of outlets, but number of outlets. At 39lb, It is substantially more robust than the 15lb P-1800. It retails for more than $1,500 more than the P-1800 but sells for only $300 more. |
I think I would plug it into the analog. My reasoning is based on the linear power supply in the AVR. You can always try it both ways. Listen for differences. Look at the photo of the power transformer inside of the AVR. Power transformer is on the front left hand side. I believe that is a Bobbin type power transformer. It doesn’t look an like EI transformer to me. // Side note. When you receive the Furman P 2400 and plug everything into it make sure the plugged in equipment with power transformers, like power amplifiers, are powered off. Because of the VA rating size of the Toroidal isolation power transformer in the P 2400 the initial turn-on inrush current will be fairly high, then quickly fall off. You don’t want to add any loads on the P 2400 transformer to add any additional inrush current onto the 15 amp circuit breaker in the electrical panel, that may cause it trip open. (Unless the P 2400 has a soft start circuit built into it to limit power-on inrush current.) ??? The bigger the VA rating of a power transformer the better, when used to feed power amplifiers. . |
