The truth is that banana plugs, just like everything else, have benefits and drawbacks and it’s important that you know about these in order to decide for yourself whether or not to use them in your system.
The main benefit of banana plugs is that they offer an incredibly easy way to create a secure connection between your equipment. Trying to thread the bare end of a wire through a terminal can be extremely fiddly, and it can only take a small bump to knock the wire out and sever the connection.
With banana plugs it’s a simple matter of pushing the plug into the jack, and hey presto, you have your secure connection. These plugs also make it much easier to connect and disconnect the cable, so if you find yourself unplugging your cables on a regular basis – perhaps you have several source devices using the same output device – then banana plugs could really make your life a lot easier.
They also tend to look a lot more professional, which is important to some people who have their equipment on display. Of course if your equipment is hidden away in a cabinet then it doesn’t really matter what your connections look like, which is why a lot of people argue that banana plugs are a waste of money.
