I'm using this filter with an iFi SPDIF iPurifier2, which gets its power from a computer USB port. It's reclocking the Toslink signal coming from a Samsung TV. I'm also using an Audiophonics Digirescue after the iFi unit to reclock the signal one more time. The Digirescue is powered by an iFi Elite. Using both of these units in this specific order, with iFi first and Digirescure second, makes the sound by far the best in my system. I've tried every other combination of using no reclocker, only one reclocker powered by iFi Elite, and the two at the same time. Using both sounds best, and by adding this Supercapacitor filter for the iFi and its dirty PC power source made the sound leap to the next level.
I also have a USB source, and before I added this Supercapacitor filter the SPDIF source was a bit worse than my USB source. But with this filter in place the SPDIF signal is now better than USB by a comfortable margin. These supercapacitor filter products are probably the most cost effective method of removing power noise. In my system it exceeded expectations. Highly recommended!
