Give them more time to break-in, most Paradigm owners report that it takes a good 150 - 200 hours for break-in. Don't worry, they'll sound just fine in a few weeks and will certainly better the performance of the Monitor 7s...
I agree with RW above.
I have the 60v2's and they do take a VERY long time to come into there own, I'd say 200 hours is not unusual. Some of the depth issue you may have may be more with your Denon and source (CDP) than to do with the studio 60's. Also you will need to play with the placement of the 60's, it took me many hours, lots of listening and lots and lots of moving them around. Much of the time moving them only very small amounts in many, many directions and varying degrees (i.e. closer together, further apart, closer to the wall, further out, less toe-in, more toe-in). Keep at it the 60's without question should out class the Monitor 7's by a far margin.
Good luck, Happy listening and a Merry Christmas.
