McCormack DNA-1 Rev A question

I was fortunate enough to have purchased a DNA-1 Dlx Rev A from a fellow Audiogoner. The amp that it replaced is a DNA-1 Deluxe. Yes, I am moving up the food chain, and boy does it taste good. The question I have is what is the purpose of having 2 sets of Cardas binding posts for right and left channel? I know this is a 2 channel amp. I just connected my speaker wires to the bottom set of posts. My original Deluxe only has 1 set of Cardas binding posts on the bottom and it looks like there are some screw type of binding post above that. I couldnt figure this out so I had to ask. Thanks for your responses

If you are considering bi-wiring, and for what ever reasons, some speakers seem to appreciate it more than others, I'd suggest using 2 separate runs for each channel.

Swampwalker, just for clarification; I thought "shotgun biwiring" is when there is one + and one - on one end of a channel of speaker cable and two + and two - on the other end of the same channel of speaker cable. I thought what you described is typical biwiring, either with seperate dual individual runs of speakers cables for each channel with one + and one - at both ends of each dual run, or combined/connected runs of speaker cable with two + and two - for each channel at both ends.

Swampwalker, I guess your right re: different ideas of the semantics involved. My idea of internal bi-wiring is the appearance of one cable with 2 + and 2 - on both ends for each channel, and external bi-wiring is two separate runs with 1 + and 1 - at both of ends of both separate runs for each channel. And shotgun would be 2 barrels from one trigger. :-)

Agreed.
