Solid and easy to install
Size: Standard--black
These are nice, solid wall mounts. They assembled quickly and easily, and they can hold larger bookshelf speakers like my Cambridge Soundworks M60s. Adjusting the plate to match speaker size is pretty easy, and they seem to grip the speaker tight enough that they won't fall off. The tilt option is very useful and a good feature when speakers are mounted high and need to tilt down toward the listener. Just remember to tighten the bolt on the bottom once you've positioned it where you want it. I would definitely recommend these to anyone looking for solid, well priced speaker mounts.

Sturdy solution
Size: Standard--black
I needed a way to mount rear speakers and this was the solution. They're sturdy and adjustable to fit reasonably sized speakers. They also pivot up and down and swivel so really perfect.

Nice unit
Set name: 5.1 Receiver
I'm really happy with this receiver even though I don't have any speakers hooked up to it. Not using it for a speaker setup might sound like a waste of a product to some people but honestly I'm finding plenty of value in it with it's other features.
The main reason I looked into getting a receiver was so I could have multiple hdmi devices hooked up to my monitor. I looked into hdmi hubs but there are a couple reasons why I've chosen a receiver instead.
1. Reliability and ease of use. Ok, so like I said I use a monitor in my room, not a tv. Monitors don't have remotes so anytime I want to change the volume or hdmi input I have to do it manually. It's a 32 inch monitor about 3 feet to the side of my bed and it's a nice arms stretch to do so. Not a big deal and while there are plenty of hdmi hubs that offer remote changing or automatic changing I worry about the reliability of those devices. There are plenty of reviews that state their hubs stop working after some months or the automatic hdmi switching starts changing inputs randomly or getting black screens and such. I just didn't want to hassle with things like that.
2. Bluetooth connectivity. This was another feature that I was looking into. Again, there are separate devices that offer this but just like hdmi hubs you will find plenty of reliability concerns. On top of that there's audio lag and previously when I bought a bluetooth transmitter I had to return it for that reason. Nice thing about this receiver is there is an adjustment for the audio to increase or decrease the audio timing but luckily it isn't an issue and the audio seems to be timed perfectly with my bluetooth headphones. It pairs up quickly too.
I haven't tried the 4k upscaling with this receiver because I use a 1440p monitor but it's nice to know that it's there. Maybe in the future I will find a use for it. There's also some neat audio presets for things like movies, music and gaming. It's actually a pretty extensive list. I suppose I should also mention that each hdmi input can be named to your liking for a nice customization feel so when you flip through them you know exactly what's connected to that input. You can even use the hdmi ports when the unit is in standby mode but you won't be able to use the bluetooth connectivity.
In the end I think this was a good purchase. It's priced reasonably and I'm getting good use out of it. Sound quality is great and the customizable features are a definite plus. More expensive than getting an hdmi hub and bluetooth transmitter but I think the reliability and extra features make up for this.

Yamaha quality!
Set name: 5.1 Receiver
Excellent sound quality. Easy setup. Complicated audio menus take awhile to master, but once you do you'll be rewarded with amazing sound. Works flawless with my 4k projector and computer. 4 hdmi inputs handles all your audio and video. The auto labeling feature is amazing. I've been using it daily for two years and it performs perfectly. You'll need an external subwoofer amp which is a bit of a let down. I bought one of the small Fosi amps from Amazon that handles the bass flawlessly. Overall, an excellent receiver that will be the centerpiece of your audio and video system. Couldn't be happier. Buy it if you're on the edge of purchasing a new receiver!
