Some food for thought: Your Vandersteens are 8 ohm and since you'll be using your 275's in parallel, you will be using the same 16 ohm taps (for your speakers) that the jumpers utilize as when set up in parallel.
The MC275 in parallel - 16 ohms = 8 ohms, 8 ohms = 4 ohms and so on... You could use the 8 ohm taps (really be 4 in your case) without any doing any damage, but you're likely going to lose some mid-bass. (I saw that the Quatros have powered woofers and only drop down to the 6 ohm region)
That said, if you use bananas to connect your speakers, you may want to re-think spades for your jumpers. The reason being that if using bananas, the spades will need to be 1/8 - 3/16" thick to make good contact with the base of the binding posts..... Spades all around if you go this route or jumper "bars" and bananas would be my suggestion.
I'm no expert, but I do own a 275, use bananas, and can read a tape. Hopefully, if nothing else, this provides some practical advice.
Congrats and good luck, you will love these amps. Please let us know how they sound with the Vandy's. Should be a wonderful match.
