Very good product with marginally satisfactory dimensions and weight, although I would prefer it to be at least 4.2 kilograms and above, and larger in appearance. It has plenty of metal, but I would like it to be a media center, with an internal hard drive for storage and not for Blu-ray recording since that is supposedly prohibited, at least from 1 terabyte. The SD card-micro card input, which is very basic, is missing. It is a 100% digital unit, and for this reason, there are no analog audio ports, only digital ones for use as a transport. I would like it to come with 2 remote controls, one that it already has, and a desktop keyboard. Overall, it is excellent.

I will make a more extensive review. At first glance, it is an excellent, sturdy construction, both in design and quality. I really like music and cinema. First, regarding music, and having a collection of genuine SACDs and DVD-audio, but also many burned discs. I have to say, I don’t know why, but it simply won’t play the burned ones. I have two other similar devices and they have no problem with this. But as for the rest of the music, the incredible clarity and detail of the sound are striking. So far, so good. I don’t mind the lack of an analog output, nor the lack of an LCD screen, as much as I could say a more modern menu, it has some strange settings. Regarding the image as a Blu-ray, okay, it’s Bravia, but still, something seems to be missing. It also has a very inconvenient menu, and you need binoculars to see the subtitles. As a media player, it is a big disappointment. And that was another reason I made the purchase. As previous reviewers have mentioned, it doesn’t play all files, and Dolby Vision is weird. It also doesn’t play many audio files. Again, there are many negatives even in simple functionality, and all these things are troubling, strangely enough.

In conclusion, as a Blu-ray it is a serious proposal and as a music device it is a unique opportunity. But as an operating system and menu, I am quite dissatisfied. Because we are talking about modern technology and, moreover, Sony. What else can I say? I wish the company would make some upgrade and make our lives a bit easier with new firmware. Because for 300 euros, to use it as a simple CD player and maybe a Blu-ray with ridiculous subtitles, it is completely unprofitable. Nevertheless, I like this tool because it plays amazing music. But only with genuine discs. Thank you, and I hope I helped in some way.

I worked on the machine and finally concluded that some things are unacceptable for the size of Sony. It doesn’t play Atmos or Vision on many files and via Netflix. It doesn’t play many discs unless they are mastered. It is an unacceptable media player. There are free codecs for programs that play, for example, mkv with DTS sound. Unacceptable operating system and menu. I don’t know what all this is due to. Sony should have more respect for its customers. Just good picture and sound are not enough, and even those only in certain cases. I keep it to play the occasional SACD, DVD-audio, and rarely watch movies on it, as you rarely find good 4K movies. I feel great disappointment.

Very good, it is worth it, it plays many file formats, the only downside is that it plays files with low mbps, it cannot play fast discs mp4 100 to 150 mbps

The image quality is amazing, it makes a perfect upgrade. As for the sound quality, it produces a "hard-metallic" tone, which sometimes sounds impressive, sometimes not and tires the ear. Sony always had excellent image but not sound. At the moment, playing super audio CD, they should have also included a simple stereo analog audio output. What would it cost? Oh, the cost-saving spirit of companies. That's why I save in my rating and only give three stars.

It is an amazing device for using blue ray discs or audio CDs.
A heavy device that screams good build quality and a very nice finish.
Unfortunately, it does NOT play DOLBY ATMOS on NETFLIX or movies from a hard drive that are in Dolby Atmos format. Very disappointing. Also, I would like a backlit remote control.

I have had the product for about 1.5 months. During this time, I have played three movies from genuine 4K UHD Blu-ray discs. In two instances, the playback suddenly stopped in the middle of the movie and the device shut down. I don't know if it was a coincidence, but it has made me worried. The colors are slightly more vibrant than necessary (perhaps it's the discs that were played). The sound from genuine music CDs is very good, but I didn't buy it for that. There are no controls on the device itself, everything is controlled by the remote. I am cautious, time will tell.

Update 11/2/2021
After a satisfactory period of use and having played more genuine Blu-ray discs, I can confidently say that the issue with the colors mentioned above was specific to certain discs and not a general problem. Overall, the colors and resolution are now absolutely satisfactory and of a very high level. Also, after a software update, the issue with playback stopping has not occurred again. Excellent performance in streaming music from a home network, with very good sound quality, no buffering, and control via an Android app on a mobile device.
