I have the same Furman Elite 20PFi. It has power factor correction that consists of huge inductor and capacitor as a filter and the energy storage for the amp. Linear power supply in your amp draws current in short spikes of very high amplitude. That's why you normally need hefty power cord with good frequency response. Furman provides 55 amperes of peak current to the high current outputs while presenting resistive load to mains. I made short Belden (Teflon) power cords for my amp and DAC but use original stock cord between Furman and the wall. My guess is that different power cord won't change much, but I'm very interested what you'll find.
Replace stock power cord that came with Furman Elite 20PFi or stock is good enough?
I recently picked up an open-box Furman Elite 20 PFi power conditioner. We frequently get power outages where I live, so the Furman is a little insurance.
The stock cord is 12 AWG. I was thinking of replacing it with an Analysis Plus Power Oval 10 or Power Oval 2.
I have a integrated tube amp and Nottingham Analogue Interspace Jr. TT. Both PC cords on these are also stock but the PC on the Nottingham is not interchangeable. It's connected directly to the Nott's motor.
The cost for a 4 ft. Power Oval 2 is more than I paid for the Furman, so it may not be the most cost effective upgrade..
