14awg from Monoprice will be fine. If you're going to put techflex on them and make them look all purty...buy the in-wall speaker wire. I just got 100' of their 12awg in-wall and it's very nice. They never seem to fail me with great stuff at great prices
For plugs...I've heard quite a bit of negativity towards Monoprice's banana plugs. I went with Sewell Deadbolts (from Amazon) and love them. Very nice looking and secure. Just like the much loved, but much more expensive GLS and Monster plugs.
Banana plugs are a great convenience item. I purchased "dual-screw" plugs similar to the one in the pic below from a Hong Kong vendor a few years ago. Great price, quick shipping...and I've never had an issue with them.
The monoprice plugs are garbage, they are highly inconsistent, I have them and hate them. You have to remove the colored ring in order to get them to clamp down far enough, the banana loosens up, and some of mine are nice and tight in the connection, others are just really loose. Sorry that products a loser even though most of their other stuff is decent.
I bought a pair of these . What do you guys think? Ive been told its great if you dont take them out once they are in they are nice and have a snug tight fit
(Have not tried them yet) but it has dual screws which does grip those wires tight....
I went with the GLS lockers for several reasons, ranging from price to the fact that my surrounds plug into jacks in the ceiling and gravity is a bitch.
I have no complaints, except that the screwdriver that came in one of my twenty packs does not work once the torque on the screw reaches a certain point... The shaft begins twisting in the handle. Between the fact that I have another one, and plenty of other small screwdrivers to use instead, I don't let that bother me.
These plugs look good and work well, and the locking feature is quite effective. You just need to twist the barrel of the plug while holding the base steady and you get a very secure fit. You can get a secure fit as well with other plug designs, but I always feel like this comes at the price of additional stress on the mounting hardware when using a friction-fit design.
