Farewell to all. I got tired of waiting for a replacement unit for the AVP-A1, bought the Anthem AVM-60 plus the Samsung 4K player and the LG 65 inch G6 OLED TV and installed 4 Paradigm in-ceiling speakers for Dolby Atmos. Major 4K CEC hand shake issues, now resolved. The ARC room correction is done, limited to 5Khz. My early impression is that low frequency performance is better than with Audyssey XT32. I detect a slight boost in mid-frequency, female voices on tracks I am familiar with sound warmer. Can't say much about the high end, have significant decrease in hearing acuity above 14,200 Hz. The need for USB firmware updates is a pain, the Ethernet port does not allow for remote diagnostics. Overall am happy with the performance, though. Thanks for all the helpful advice posted on the forum over the years. Best wishes to all remaining forum members.
