@rmjg36, glad you are liking the SteinMusic Harmonizers. We are dealers for them in the UK. The sound with them becomes much more open and natural I find. I’ve been using them for about 2 years now and consider them as an essential part of the system now. I have them in the corners just behind the speakers. They combine with blue suns and diamonds, two of which are on the rear wall about half way up and two are on the side walls in line approx. with the speakers but high up towards the ceiling. Definitely experiment with the positioning and two more H1’s might be good along the rear walls.
Stein Harmonizer's
The other night a dear friend and major audiophile brought by three (3) Stein Harmonizer's. We were simply stunned by how much they improved my system (Devialet 220/Harbeth 30.2's/Nordorst, Red Dawn speaker cables/Torus TOT AVR). The soundstage, clarity, dimensionality etc. were greatly enhanced. Has anyone experienced anything similar? I was utterly incredulous until I heard the difference/improvement.
