When do you need a power conditioner

Good advice from Tls49. If you are in a house, 2 lines would be easy and recommended. BTW, "dedicated line" means your system would be separated from the rest of the electrical and have it's own breakers. No more interference from sharing AC with the lights, fridge, etc.

If not able to run a line, the right PC would improve the sonics of a system and would provide a lower noise floor. Research the archives, lots of info.

Thanks everyone, I will look into it.

Question, getting a dedicated line is out for me. I have a great deal on a Furman Elite 20 pfi, now this unit comes with a 15 and 20 amp power cord, since my outlet will be a standard 15, will this work, or should I just be looking for a 15 amp line conditioner?

Dedicated line (or 2) 1st. Then consider power conditioning especially if you live on the grid.
