Also, all the daytons I've tried are gold palte over cheap brass, or worse, gold over nickel over brass. The dayton banana adapters sound noticeably bad comapred with bare wire.

I would be suspicious of any connector that doesn't specifically state that it hasn't any nickel.

I've been delighted with Eichmanns (what a name, not his fault of course) and the brass Vampires. They cost a lot more than the ones in the link or the Daytons but make a difference I can hear, dammit. I suspect there is more to the connectors than to the wire or geometry.

Every once in a while I plunge for a pair of Vampire 800C which are gold over copper, no brass but very expensive. I now have enough for 1 pair of IC's. I'm doing that because of the great sound from a close-out phono cable I bought for 50 bucks that is terminated with the 800C. Can't be beat.

Also, I just replaced the AN silver speaker terminals on my 45 amp with solid, unplated copper Edison Price Music Posts. I can hear that change as well, more than any difference between the anti-cables, twisted pair Cardas Litz I made or some very expensive review cables I currently have on hand. The Music Posts also put a death grip on any spade. Finger tight means needing a screwdriver to get them off. No kidding.

Now, back to the game; Indians up 1-0, bottom of the third.
