This is a set of Acoustic Elements from Stein Music. They can be used in conjunction with their H2 Harmonizers (for greater effect) or on their own like what the previous owner did. The set you see here comprise of 2x Black Stones, 2x Black Diamonds and 2x Blue Diamonds. They each sell for $50, $185 and $350 respectively. The Black Stones were previously used by placing one behind the listening chair/position and one in the front and center point between the left and right speakers. The Diamonds (Black or Blue, which ever you prefer) were placed on top of each speaker.
Cosmetically, the unit looks good. Minor scuff marks/nicks from use but nothing major. Units will be securely packed for safe shipping.
