How good are these.....?

[E-Stat]

Are these cheap banana plugs on ebay any good...or would I be better of paying more for good ones?

...And also is this RCA cable any better then a 'normal' rca cable:

My experience is that cables can most certainly make an audilble difference, but ---

One must put any recommendation into perspective. What is the related system? What kind of music do you listen to? How acute is your listening skill? Do small audible differences matter to you? Naturally, the differences will be more apparent on higher resolution systems listening to better recordings, usually of an acoustic nature. For the vast majority of systems, however, those cables you listed should be fine. Or those found conveniently at a local Radio Shack.
