I just bought 40's v2. I had same experience with you. They sounded boxy. My old speakers B&W DM630 sounded better. My amp have spk A & B selector so I can compare them side by side via remote control.
I just tought to sell them back after 1 week, but I didn't have time. So I just hit them with disco and pop almost everyday. After 2 months I finaly found the 40' sounds so much better than B&W DM630. Now the B&W sounds muddy, less details, the bass not tight, but I'll keep them (the B&W) to be the evidence for the better sound: Paradigm Studio 40's. Now I am looking for the 100's.........
