Review after 3 months of use.Bottom Line Up Front: I'm very happy with the unit for the price I paid for it. Sound is clean and its intuitive to use.Setup: I replaced my Sony STR-DE595 with this unit and am very pleased. I have my unit wired with 14 gauge wire with Gold Plated Banana plugs. They are strung to a 5.1 pioneer sp-fs52 Andrew Jones config. I have a PS4 Pro (4K) run though the unit (HDMI) along with my Smart TV (4K) via Optical output.Pros:1. Total system configuration to remove my old system and connect this unit while replacing all speaker wires and plugs took about 45 minutes to an hour. I like to take my time.2. Speaker calibration was as simple as connecting the mic provided and running to easy setup function via the on screen menu.3. Bluetooth was easy to pair. I love the clarity via the amazon music app.4. Clean front profile. I know some people like having a lot of button on the front of their unit but I like how they digitized the menu via your TV.5. 4K pass-through is legit. I play 4K game on my PS4 Pro all the time and notice no delay or out of sync sound/video like other brands have. This is key for those of is that play FPS and reflex/reaction time sensitive games.6. Audio via optical has been excellent so no complaints.7. Remote is easy to use along with the menu once you learn the where to navigate to. Typically though there is little need to go into the menus after you've configured it. The remote has all the most commonly used featured on it so that makes it easy.8. There is an auto-sleep feature that will turn the unit off after a period of inactive audio time. This is nice however some people have complained about the unit shutting off while watching TV while they are using a head set with say their PS4 or direct from source audio. All you have to do is turn off the auto sleep feature from the on display menu.8. This unit uses the smart HDMI features (ARC). IE if the unit is off and you turn on your PS4 Pro or Smart TV the receiver will also turn on. Same goes for turning off. This is nice so you don't have to go fumbling for all your remote. Note! Your TV and any other HDMI device must have ARC support to use this ability however its not required for basic operation. If your device does not have ARC then you would power down your units separately like you do with older systems.Cons:1. Not that much of a con but its significantly larger than my older unit however its still sized for proper entertainment shelves.2. Have had some issues with connecting to the Bluetooth from time to time however unsure if its been my phone or the unit. I will update after more trouble shooting.

I had recently put together a 5.1 channel home theater system in my bonus room, as well as a Vizio 4k TV, and needed an A/V receiver that could support 4k video as well as 5.1 channels. I had come across this Sony receiver on Amazon and, for under $200, it met all of my requirements on paper. Having owned multiple Sony products in the past, I decided that I couldn't go wrong with Sony's STRDH770 A/V receiver. Here is my review of the Sony STRDH770.Setup:Setting up the STRDH770 was very easy and took very little time (excluding the time it took to plug in the speaker cables). Once all the speaker cables were connected, I chose the Easy Setup option which prompted me to plug in the calibration microphone that came with the receiver (it looked like a small black disk) into the calibration mic port on the front of the receiver. Once I did that I began the speaker calibration which mapped out where the speakers were relative to the listener. The speaker calibration took less than a minute and was extremely simple.---------------------------------------------------------------------------------------------------Design:Before I get into the design of the STRDH770, I want to tell you that this receiver is a lot bigger than it looked in the pictures. It measures well over a foot wide and a foot long, and is almost a foot tall. It surprised me how large it was, but I don't think that will be a problem. The STRDH770 has a nice, modern design that looks very premium. There are two large dials on the front to select the input and adjust the volume, however, even though they look nice I was disappointed to find that they were made of plastic and felt very cheaply made. Most of the receiver is made of plastic, however, this shouldn't really be much of a concern since it will just sit next to your TV for most of the time. I am not very upset with the build quality of the STRDH770 especially when it only set me back $200. Overall, Sony did a great job of making a receiver look premium while only costing $200.---------------------------------------------------------------------------------------------------User Interface:The Sony receiver has an extremely simple menu, consisting of 4 different options to choose from - watch, listen, easy setup, and speaker setting. Selecting "watch" takes you to your different video connections, while selecting "listen" takes you to Bluetooth or FM radio which you can listen to by plugging in the tiny FM radio receiver included in the box. You can also connect your phone to the receiver via NFC (Near Field Communication) if your phone supports it. When you first use the receiver I would recommend choosing easy setup, as it is the fastest way to configure your home theater setup. However, if you want to fine-tune your speaker settings you can select "speaker settings" where you can change the audio gains and the distance each speaker is relative to the listener. The user interface on the Sony STRDH770 is simple and basic which isn't necessarily a bad thing, and is what I would expect from a budget receiver.---------------------------------------------------------------------------------------------------Features:The STRDH770 has quite a few features for costing less than $200. For one, it supports 4k video with HDR, so if you have a 4k HDR TV this would work well with it. The receiver also is compatible with NFC, which, if your phone supports it, is much easier to connect with than Bluetooth. As far as sound goes, it features HD-Digital Cinema Sound, which, for most people sounds great. The Sony receiver also features a few EQ settings such as Movie, Music, and Night Mode. Night Mode boosts vocals so that you can hear what people are saying while watching something at a low volume. For me at least, this receiver sounds great and is well worth the low price of $200.---------------------------------------------------------------------------------------------------Connectivity:One of the best things about this receiver is the number of HDMI ports it comes with. The STRDH770 features 4 HDMI in ports and 1 HDMI out which goes to the TV. Right now I have an Xbox, a Bluray player, and a cable box hooked up to the receiver and I still have one more unused port. I don't see why anyone would need over 4 HDMI ports especially when a device such as an Xbox One S can function as a gaming console, a streaming device, a Bluray player, and a cable box pass through all using just one HDMI port. Also, as an added bonus, Sony included NFC and Bluetooth with this receiver. Overall, I think that, for connectivity, this is the receiver to buy if you have a limited budget.---------------------------------------------------------------------------------------------------Conclusion:Overall, I think Sony hit this one out of the park with the Sony STRDH770. For under $200, you really can't go wrong, and I doubt that someone could find a better 7.2 channel 4k receiver for under $300. If you are looking for a great, 7.2 channel receiver that is compatible with 4k HDR video on a tight budget, look no further.---------------------------------------------------------------------------------------------------Pros:- Great design- Easy setup- Sounds great- Many HDMI ports- NFCCons:- PlasticIf you found this review helpful I would appreciate it if you clicked the "helpful" button below this review.
