I have used all manner of connections, and do not have the ability to discern any difference in sound quality. However, I can tell you that if you like doing A/B speaker tests, bare wire connections will be the first to suffer repeated binding post torture. If you aren't swapping cables that frequently, bare wire should please you for it's connection and non-existing "connector" price...
If you want the absolute best connector, please contact me and I will be happy to provide you with the world's most expensive Unobtainium Connectors. I will charge you so much for them, you are bound to get otherwise impossible compliments for your intelligence and excellent choice. Your marriage may suffer, but if you are after Unobtainium to begin with, it's unlikely you have the problems that a marriage can entail. Good luck!
