I replaced an older “SC” model with this unit about 2 weeks ago. Although the sound quality is pretty good, these new units are nothing like the older Elite units. We have been installing custom home theatres for 30+ years. Pioneer used to be my go to unit for custom installations but after the Pioneer/Onkyo merger, this unit is more Onkyo than Pioneer. The rs232 protocols are quite unreliable when used with custom integrations. System reprogramming is a nightmare. I must say we were very disappointed. Sent from my iPhone using Tapatalk
