"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.

Specifications

  • Type: Battery-powered room harmonizer

Men's Cargo Shorts

Not true color. Ordered Kahki color shorts, instead got ugly yellow/orange color shorts. Fit ok will see how they wash. Still considering returning.

Comfy shorts with plenty of leg room.
Size: 46, Color: 01khaki
These shorts run huge, in the legs. Nice material, well made, waist was the right size, but too much in the legs.

Great watch. Would buy again if I live that long.

Excellent product. Simple, reliable, accurate and easy to read day or night. Don't think about it too much. Just pull the trigger.

If only it had Indiglo....
Color: Black
Terrific watch. The leather band is very comfortable right out of the box. The bezel is crisp with very little slip. The markings are very good in the dark, but I still wish for Indiglo.
