adding a connection to audio path
I know its not needed but doesnt it give a better connection than bare wire? What do you mean by "adding a connection to the audio path".
In the electrical path you are adding another point : bare wire to banana plug to speaker terminal, where before it was bare wire to speaker terminal.
Normally it is a good practice to minimize the number of individual items in an electrical path ( or any other system fro that matter) to minimize the number of points of failure.
Hover IMHO putting a banana plug on a wire has very, very minimal impact on reliability and introducing a new point of failure.
Bare wire is fine, you just need to spend time, maybe even extra time up front to insure they are exactly the right length ( too short not enough contact , too long posibility of shorting) and to insure the braided wire is twisted so that it is like a single solid cable so there are no wire whiskers that can cause whisker shorts ( sometime whisker shorts are not obvious at low volume and cause AVR overload safety power trips at higher volumes).
I like banana plugs becuase of secureness of connection and the ease of conencting if you even do updgade or cahnge like most audiophiles do.
For a similar reason I do not like spade connections at all. The connection must be tightened and physically secured or a spade connection can easily come loose, even more so than stranded bare wire , becuase stranded bare wire is somewhat compressible and acts like its own lock nut.
...enough of my rambling
