Oh, about 15 years ago, one of my local high end audio dealers introduced me to audio "Tweaks." I was absolutely floored by the positive and amazing effects that each tweak made on the sound quality of the music. Whether applied to speakers or components, or both, the improvements made by tweaks were real and palpable. I've been a true disciple of audio tweaks every since that faithful day about 15 years ago. Recently, online, I stumbled across an article touting all of the wonderful virtues of a tweak that I had never heard of before, the Puron AC Conditioner, so I decided to order one and give it a shot in my highly revealing audio system. All I can tell you is......WOW!!! I had already had speaker bullets/filters on my speakers, and Vibrapod feet and cones on all my components, but the Puron still made the soundstage noise floor even lowers and blacker and the effects were just amazing. Even more depth, spaciousness, air, detail, transparency, separation, palpability, increase sense organic sound and a smoother musical flow are how I would describe the effects of the Puron. I'm please to tell you that, in my experience, the Puron AC Conditioners was absolutely, "As Advertised." Along with my Bybee Tech Speaker Bullets, the Puron is one of my greatest audio purchases. Well done!!!
