Why my system has detail but no body & warm vocal?

Our systems are similar. I have the 602s & Rotel RCD 951, and use Kimber Interconnects as well. In the first months of having the 602 I was plagued by that thin sound/lack of warmth you describe. I think I considered replacing my components too. Eventually it occured to me to move the speakers off the short wall. What I discovered was that the 602s like space, not only to be a couple of feet off the back wall, but to be spread out-6 feet at least, in my case. I discovered that my furnature acted as a sort tone control. Lots of soft furnishings the sound gained some warmth-too many direct hard surfaces and it became too thin and bright. It went something like that, the point being that these speakers are sensitive to their surroundings. Once I made these observations and made some efforts to address the rooms effect on my speakers the sound evolved to something more to my liking. As well, I noticed a solid stand really improved the bass in the 602s, as well as giving the sound some added impact/solidity. They were very sensitive to speaker cable, or more so than the interconnects. Once I changed from 16 gauge to 12 gauge the sound gained even more presense, and this was not at any substantial expense even as I was biwiring.Finally, the 602s are a quandary. They can sound incredible one moment and horrible the next. I would not say they were the last word in neutrality, but you definately get to enjoy the quality of recordings you listen to. In this the 602s can sound distant or veiled one moment, bright and edgy the next. It took a long time for me to get used to that, and it is something that I have come to appreciate.Very finally, I never enjoyed my rock recordings with them. I have read so many reviews of them where the reviewer felt that they really kicked loose. I never had that experience. I dont doubt that those reviewers are correct in this. I just dont have a set up that exploits this particular attribute of their many fine qualities. My advice is to take the time to experiment with placement and the room environment first, then perhaps stands and cables.
