Should I upgrade the cable of my Line Conditioner?

Most likely would make an improvement as others have mentioned. Many times it depends upon your selection of power cords. How much ($) are you willing to spend, then perhaps you can get some suggestions.

I also use Furman Elite-15 Power Conditioners in my system. I did upgrade to better cords. For me, it made a nice difference. Although, for me - I would upgrade cords to my amp, pre-amp, CD transport and DAC first. Those had bigger bang-for-te-buck returns in my system.

I like my Furman. I say leave it alone.

it’s the internal capacitors that send the juice to your equipment. you can fill them with lousy juice, they will send exactly the same out.

Very important cable upgrade it asap.

Do you have an aftermarket cord that you can borrow from another component (one that you would not need to use)?
