gritter2,
I have two pairs of speaker terminals, so no problem here. In your circumstance you can stack the spades (Clear Day cables are terminated in relatively thin but high quality silver spades). What you could ask Paul is if he can run both pairs of Double Shotguns into one pair of spades at the amp end. Note: Paul uses smaller high quality silver spades at the speaker end to accommodate to the terminal strip at the back of the Treos as it is hard to fit full size spades. In other words, if you call Paul and discuss it, he will tell you what he can do.
As you can tell from your thread, Paul's cables mate well to Vandersteen's as many of us have had the good fortune to use them in our systems. I would strongly suggest you give Paul a call and chat with him. At worst, you'll have an enjoyable conversation. He will be straight with you and not pitch his cables. They speak for themselves. 👍
All the best!
