This is a Room Acoustic Treatment Set which comprises of two Harmonizers (H2a and H2b), its accompanying stands (new and only taken out for the pics you see here) and two Black Stones. In our listening session, we tried them with a music track that we were familiar with, we turned the Harmonizers on and boy what a difference it made! The vocal soundtrack that we were using took on a more “bodily” imaging. The highs were a bit more extended and the music generally felt more energetic, more “alive”. The previous “setting” we were familiar to, became more focused. Musical instruments were more accurately placed in the sound stage. It was quite simply, an amazing change. Little wonder now why Stereophile was singing praises on the Harmonizers. Different rooms will reap different results so adjust them accordingly via its intensity control knob on the rear. They are battery operated (batteries not included) with 4 AA batteries in each unit.
These were former dealer demo units and will be shipped in their original boxes. This will be a two box shipment where the stands (just the aluminum rods) are shipped in their own box and the Harmonizers, stones and plates for the stands in their own separate box. Cosmetically, they look very good with minor scuff marks from use but nothing major.
