I Still enjoy my older version STR-ZA5000ES (from 2016). I coupled it with my 3 Channel Anthem MCA 325. The set up is perfect for my ears and needs at this time. I’ve been rocking on approx 7 Sony receivers since the 1990’s. Right before the one I have now, had the Sony DA5000ES. It replaced Sony STR DG-1200 that I still use daily in my office. It is 15 years old and starting to get some heat problems requiring a loud fan to keep it going. I will be upgrading it to something that serves my needs for the office. The STR-DA5000ES (2003 release) hit protected mode too many times and I gave up on sending it to Sony each time to fix. I believe the problem was too many ethernet ports and I used them and it heated the thing up beyond usable. I avoid more than 1 ethernet port use now. Sony’s Bells and whistles with the Connect 4 lights and other items to me were not of value. \nWhen I upgraded to the ZA5000ES I was pleased for everything except no headphone jack. Then I got the Monolith headphone amp and I was happy again. The sound upgrade was at least 30% better than previous model. Unsure why but it sounded clear at even the louder levels. Major improvement in sound. I also have Dennon and Yamaha receivers and just prefer the clearer more neutral sound of the Sony top of the line. \n\nI have not heard the new Sony Amp in this review but I don’t see I need it yet. I’m very happy with my set up for living room. If someone compared the new 5000 to my prior models that would be of help. The reviews I have found did not compare to the older models. \n\nMy only suggestion for Sony would be to include some of the SDDS sound features that my STR DG-1200 had. Many Movies we have end with the Credit to SONY SDDS sound. Truly you have seen this on so many movie credits and I have never heard one comment on how to get it! I have it on my older Sony receivers. I have experimented with Neural X and Dolby Digital surround but nothing compared to the 3 choices Sony offered.\n\nHere is an explanation of what was..\n\nDigital Cinema Sound (DCS): Digital Cinema Sound is the concept name of the surround technology for home theater developed by Sony. DCS uses the DSP (Digital Signal Processor) technology to reproduce the sound characteristics of an actual cinema cutting studio in Hollywood. When played at home, DCS will create a powerful theater effect that mimics the artistic combination of sound and action as envisioned by the movie director. The DCS soundfields used in this receiver include:\n\n\nCinema Studio EX A: reproduces the sound characteristics of the Sony Pictures Entertainment "Cary Grant Theater" cinema production studio, great for watching most any type of movie\nCinema Studio EX B: reproduces the sound characteristics of the Sony Pictures Entertainment "Kim Novak Theater" cinema production studio, ideal for watching science fiction or action movies with lots of sound effects\nCinema Studio EX C: reproduces the sound characteristics of the Sony Pictures Entertainment scoring stage, ideal for watching musicals or films where orchestra music is featured in the soundtrack\n\nI understand that now Sony has 360 sound. I have it on the new SoundBar and it’s okay. But the SW5 surround speakers are weak with it. My Bedroom TV is an older Bravia that does not support the use of ERC ARC return channel so soundbar won’t work in atmos. So I’m stuck there. The Sony 360 sound is now said to be great. These new AVR's appear to make use of it per the reviews. I know it would be even better on the AVR if choices of the old SDDS modes were made available again and being exclusive to Sony, their product would boast something nobody else could get!
