@erik_squires Thanks for your thoughts. My amp is just 5W class A before it changes to A/B.
I believe the Furman model I selected is their top model & has the features you recommend… but maybe not. Your link goes to a cross Atlantic yacht trip. Can you resend?
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!

OP: So sorry about the bad link, this one should be correct. 5W is sipping off the power. Furman makes a lot of models geared towards either home or professional users. If you like that unit, stick to it. :) I was just describing why my own gear is more focused on voltage regulation than isolation. Isolation focuses on noise. Regulation focuses on keeping the line voltage as close to ideal 120V as possible, and tries to compensate for over and under voltages as they occur. The unit you are suggesting has the most important features. SMP, LiFT and EVS. That will keep your gear noise free and healthy for a long time. |

Each step will provide a notable improvement in sound quality. 15amp direct lines... one for amp (no power conditioner) and one for the rest of your components. And a good quality power conditioner. The better quality the better. I would look at Shunyata and IsoTech. Since it is likely you will replace your power conditioner nearly as often as components, it is worth getting a good one. My 75lbs conditioner won awards twenty five years ago when I bought it and has been performing incredibly well since then. |
