Most manufacturers advice against "stacking" of line conditioners because of possible interaction between the filter and protection components. Stacking will most definitely have an adverse effect on dynamics and bass impact because of the increased source impedance of the AC supply.
Stacking mains conditioners
I have a couple of pro audio Furman’s lying around that I used for my computers & peripherals in my home office. A few weeks ago I thought I’d see how well they work on my audio. I used 3 units, and plugged the first into the mains outlet, the second into the first unit and plugged the third unit into the second. I plugged my pre and power amps into the third.
I found that this arrangement gave significantly better results than a using only a single unit. Has anybody else tried this? Did you have any negative results?
So far I have not noticed anything negative. When stacking three Furmans I seem to get a lot more low level detail, as well as firmer bass and a slightly extended top over using a single unit.
The units I used were two PL-8C’s and one PL-8 Pro C.
Anybody with similar experiences?
