Just thought I'd chime in on my experience with the unit. I also had some DC issues that I'd been trying to address. It has completely increased the musicality of my headphone rig which centers around RAAL amplification and headphones. My experienced mirrored Srajan's. Deeper, darker background. Better tonal saturation and weight which was a meaningful improvement. And shockingly, absolutely no loss in dynamics. The rig was fairly dialed-in, but this has taken it to another level. Previously, power distribution was via Furutech (same as Srajan's). In the past this solution bettered everything else I've tried. Also wish it had 6 outlets, rather than 4.
I'll be adding a second to my 2-channel rig which centers around Voxativ speakers and Lyric amplification. I've cycled through a ton of different power solutions. The most involved was dedicated lines along with Isoclean units. I've also tried some other DC blocking solutions and they didn't come close to this one.
Within the context of my expectations and experiences with "power conditioning", this is a product that I'd highly recommend.
