Hello I have been a satisfied X-statik owner for several years and have never posted. My X-statiks were an AV-123 build and the crossovers were updated before I bought them. I am strongly considering adding No-Rez and Tube connectors. I have had the good fortune of hearing the great GR research rooms at the Lone Star Audio Fest in years past and am appreciative of the great value and musicality they bring to the table.
