Red, black, run right!
Size: 40 Feet
I got the TYUMEN 40FT 18 Gauge 2-Pin Red & Black Cable for hooking up LED strips, and it worked perfectly. The wire is sturdy, flexible, and easy to cut or connect, making installation quick and hassle-free.
The 40-foot length is generous for longer runs, and the color-coded red and black makes it easy to keep track of positive and negative connections. Great for DIY electronics, lighting projects, or any small electrical hookup.

CAN be used for simple Home Theater but really shines when playing music.
Style: R-S202BL, Configuration: receiver only
First: YES, you can use this as an AV receiver *IF* you have a simple home theater setup and are willing and know how to run a digital to analog audio converter from your TV to the inputs of the receiver. BestBuy sells an inexpensive and intuitive unit.
HOWEVER, if you have several devices associated with your home theater (i.e. more than 2 -- then this probably isn't a great option for you).
I generally prefer Vintage Stereo equipment -- My ideal receiver was the Yamaha CR-2020. But sadly, those are hard to come by and have are more expensive and like a used car -- you don't really know what maintenance you have ahead of you. I had inherited a Sony AV receiver that pre-dated HDMI. It worked and I could even program my Logitech remotes with it. However, it really didn't bring the best sound out of my speakers -- a pair of original Large Advents. Plus, it seemed like it was starting to give up the proverbial ghost.
My AV setup is pretty simple since I dumped Time Warner -- or whatever they are calling themselves these days. I have a TV, Roku Streaming stick and that's it! I don't have a living room that would accommodate 20 speakers and a sub without tripping over them (my cats and dog and kids shoes provide enough of an obstacle field).
The downside -- this isn't really intended to be an AV receiver. No Optical Audio in... no HDMI ports... you have to make it work if you want to use it for your TV as well. I purchased an Insignia Digital to Analog Audio converter -- you plug in the HDMI cable from your TV into the input and use RCA cables as the output to plug into the receiver. This little gizmo was about 25 bucks so I was still saving quite a bit of money over "full-featured" AV receivers.
The sound for the TV is fine -- You aren't going to be fooled into thinking you are in an IMax theater or anything. But that wasn't my primary concern.
I really wanted my music to sound great. And playing music is where this receiver really shines! I *REALLY* like the Bluetooh connectivity so that I can play from my computer, cell phone without having to use a patch cable to plug into the receiver.
It has a very simple interface -- mainly because there just isn't that much functionality. push a few buttons and you'll be able to figure it out without a manual.
I know several reviewers have commented on the flimsy clips for the speaker wire but I have some fairly heavy gauge wire and it doesn't works just fine. I don't use banana plus -- just run the copper straight in. Once you get it set up, you shouldn't have a problem -- it isn't like you are constantly re-wiring your speakers.
I was able to purchase this for less than 120 bucks and it drives my vintage Large Advents really well. It provides a beautiful full sound for a wide variety of musical genres.
Maybe one of these days, I'll stumble across another great vintage receiver. But for the money and the convenience of a remote and bluetooth, this receiver can't be beat.

Does exactly what I wanted, sounds perfect for the price.
Style: R-S202BL, Configuration: receiver only
I'm kind of an audiophile, really picky. I got this while on sale for $150 and I am really surprised with how good it sounds, it doesn't compare to the Niko amp I was using in the barn, but it powers my KX12 speakers really well, shakes the walls of the barn. I'll be taking those speakers inside for the winter along with the Niko amp and be using the YAMAHA NS-6490 speakers I bought at the same time as this. I'll be reviewing those speakers soon, they also surprised me.
The bluetooth connected easily.
I had to use a 3.5mm Aux to 2 RCA Adapter Audio Cable to connect my laptop to it. Some stereos come with a 3.5mm input, this doesn't, but neither did my Niko Beta 30 preamp, so no big deal, the adapter was less than $8.
The tuner is really good, I have this in my pole barn that is all metal, including the roof and 18 miles out of town yet it picks up several stations with the supplied antenna, my portable stereo doesn't pick up anything when in the barn.
The specs say it plays 10 Hz – 100 kHz, that seams a little much, the best ears can hear is up to 20kHz, and nothing you connect to it will go higher than 30 kHz, so why would this play up to 100? I use an equalizer to shape the sound and it does play to my satisfaction for the price, both sound quality and volume.
For the $150 I spent, this is a really good deal.
