It's been quite some time since I need to buy a new receiver. I was completely happy with my previous one which was also a Sony. The older unit was quite a bit more expensive, and higher end than this one when I purchased it. Sadly, as technology moves on, some stuff just doesn't fit in so well with the new guys! My reason for switching receivers was due to needing 4K and HDR Passthrough, something my older unit couldn't do. I don't think the 4K specification had actually been finalized when I got it, so while the sound was great, there was no way to pass 4K HDR video through it's HDMI, and no way to upgrade it.To keep costs down, I decided that this time, I was going to get something a bit cheaper, but keep with the same brand since I was happy with the previous unit, and then later on, invest in something a bit higher end. That plan has kind of gone out the window at this point.The DH790 is great for it's price. It's got all the latest connectivity, but still packs in a great sound. I haven't actually notice much of a difference in the sound hooked up to my Kef speakers. It's quite slim compared to what I'm used to as well, so I gained some space under the TV what was an added bonus.I don't want to get to into the details with this, there's no shortage of consumer and professional level reviews out there already, so it's best to get the full details from them. If your already using a receiver for a standard home theatre set up with speakers rated at around 100 - 120w, and are thinking of upgrading it for newer HDMI standards, or Bluetooth etc, my advice would be to look at something like this. It's way more affordable, and you really aren't loosing much at all. I decided to keep the DH790 rather than spending another £600 - £700 on a receiver that I can't really hear much difference in.
