I just got the Porter Ports wired to the outlet for my system and I a bit puzzled as I honestly expected zero improvement. I have called BS on the "fuse-heads" and a boatload of other tweaks I have tried and rejected. While my impressions are purely subjective, I am apt to concede that familiar music has taken on a bit more vividness and the LF seems a bit more impactful. The music just seems a bit more alive, with a greater degree of clarity. In contrast to other folks in this thread, it is nowhere close to upgrading my amplifier. Still, viscerally, I am liking what I am hearing and the $80 investment for two PP outlets strikes me as a fair price for a tweak.
At any rate, the PP outlets do grab my canted heavy power cords with far more authority than the outlets they replaced. A cheaper route would be to upgrade your basic AC receptacles to the standard non-cry-treated Hubbell 5362 receptacles, which is what the PP outlets are, and if you get an improvement in sound, that will be dandy, but for sure you will have a much more secure connection for your power cords. Cheers, Whitestix
