SteinMusic Harmonizer H2 PLUS Signature Series

"I wish I could tell you why what happened happened, but I can't. All I can tell you is that when these battery-powered cubes filled with a secret blend of crystals appeared in my listening room, everything changed for the better." — Jonathan Valin, The Absolute Sound

The SteinMusic Harmonizers have been our favorite tweak for more than ten years. Not a strong candidate, not a conditional recommendation — our favorite, period. The H2 PLUS Signature is the current flagship expression of the technology.

The PLUS and Signature Upgrades

The H2 PLUS adds a Blue Diamond element to the standard H2 configuration. The Signature level represents the highest refinement of the Harmonizer technology — more crystals, more carefully selected, producing a greater effect on the acoustic field properties of the listening room. Best used in pairs, placed near the speakers. The combination of two units creates a field effect that neither unit achieves alone.

Press Recognition

Jonathan Valin at The Absolute Sound reviewed the Harmonizer system with the quote above — a review that generated more reader inquiries than almost any other accessory review in the magazine's history. Positive Feedback has also covered the Harmonizers consistently.
