Donny, used the larger Z5500 POZ setup tonight. Still haven't had a chance to try out the Z2300’s satellites perched atop the T4 because it requires mounting them to the T4 MS04 swivel bases, which are currently mounted to my Bose 161 satellites. Remounting requires drilling holes on the bottom of the Z2300's satellites and I just have'nt found time to do that yet. Perhaps next week.
