Furman Reference IT 15i power conditioner

I have the 15 and the used to own the IT 1220.

I noticed a bit of dulling of the sound when I ran them like someonelse mentioned.

In the end I went with all shunyata .

The furmans never let me down and were great until I found something that appealed more to my personal taste in the shunyata hydras.

What I do miss are the voltage indicators on the Furmans.

Always was nice to know when the grid started to go into lock down in the summer.

I installed the Shunyata RZ71 outlet in place of one of the generic Furman outlets and that made an improvement.
I believe the stock(cheap) outlets on the Furman 15 are compromising it.
Also, upgrading the male power connector with something better from Furutech or Oyaide will also improve performance.
These are very easy and reversable mods to the Furman.You don't need to solder anything.
