Was always a Yamaha guy but switched to Denon two years ago and I am glad I did. The yamaha I purchased was awful and support was even worse. I now own 3 different Denon avrs and all have great video and audio. The HEOS has also been outstanding. Only problem is the units are imax enhanced and their has only been 10 imax enhanced disc for sale in the last 2 years. I have all ten disc and imax enhanced projectors and the improvement in both audio and video are significant from regular 4K movies. I don’t know if COVID is the problem or not but Sony and dts said they would produce hundreds of imax enhanced movies last year. Come on guys where are they? Also please give us concerts in Dolby atmos this has been the biggest achievement in audio in the last 25 years. If you think 5.1 concerts sound good you will be blown away if you heard the same concert in Dolby atmos it is a whole different animal. Again if COVID is not the reason for not advancing our technology then let’s get with it guys I’m 71 now and don’t have that many years left. Give me a chance to enjoy my hobby before I make my exit.
