2 reasons for not using barewire from hi-fi point of view:
1]The metals get oxidized very rapidly and result in deterioration of sonic transfer especially at the extreme frequencies.You will lose the 3-d image , the emotions of the performers will be missing and the ambiance of the hall will also be gone.These are the things we hold dear to our heart,andcan easily be heard in very transparent systems.
2]The amount of stress induced on the wire will be much greater.stressed wire produce muffled sound.
the solution?Use the best connectors you could afford.Bocchino and WBT{nextgen series are especially good for banana] make the best connectors IMHO
