“I was very weary and pleasantly surprised. My 300B amp is dead quiet and I use a mid-range power conditioner (that many Upscale audio folks would more likely label low-end, honestly). I knew my power wasn't particulary good, so wantted to give this a go. It serioulsy dropped the noise floor to the extent that I am still impressed weeks later. Much more sonically-valuable addition than the QK1 which to my older ears only "softens things a wee bit". So if you're like me and on a budget: save the extra money to get this one first. It's one of the better upgrades I've done in awhile.”

“I was expecting a difference that could only be noticed by A/B’ing… I was wrong: the improvement in space was immediately noticeable from the first track I played after plugging it in. The noise floor on my 300B amp I’ve been tinkering with for years disappeared like a bottomless pit. It’s one of the most satisfying additions to my setup in a while. My only regret: not knowing about this little strange device earlier.”

“Of the various tweaks I’ve tried over the years from isolation bases, wall treatments, power conditioners, the Harmonizer has been by far the most impressive. The soundstage opened up incredibly and the DETAIL of individual instruments is amazing. I’m impressed.”

“I have enjoyed a wide range of products from Nordost and the AC Line Harmonizers are awesome. The more I add the sweeter the sound gets. Nordost is an awesome company and they stand behind their products.”
