I have a Sardonyx center, which is basically a Tanzanite with an extra Seas excel.
Heres a pic of it raw with Selah Sedona arrays, these are the rears for my HT system.
I have a set of Selah Symmetricas for the fronts, and a couple of dual subs designed by Rick as well.
I think you will be very pleased with the results you get. For the price point theyre very difficult to beat.
