An audiophile who works at GG told me bare wire connection is the worst. It doesn't separate the hi/low freq. too well he said. I don't know if that's true I just know it doesn't make any sense to me. Can you guys tell me what you guys prefer. Spades? Can we use it on receivers? I have just bought a Marantz 7200 and seem to only accept bare wire and banana which I prefer not to use due to fact it that it sticks out. Any inputs appreciated.
