When a system sounds "thin," it means that there is a lack of body in the upper bass and lower midrange, which contribute to the fullness of voices and instrumental texture.
The first place to start is at the beginning. My experience with Rotel gear is that it has "detail," but is a bit on the lean side. Also, what you're talking about is "dimensionality," which is a sense of a palpable, invisible person or instrument right in front of you, either between or behind the speakers. The equipment DOES have everything to do with that.
First, ALWAYS start with your source equipment. CD player, turntable or the like. Although it may be something further down the line (i.e., interconnects or speaker cable), the source will ALWAYS show you whether or not it itself is contributing to the issue at hand.
Borrow one that has fuller sound. You mentioned the Arcam 23, which has a fuller sound. See how that improves - or changes the overall musical feeling of the system.
Then try the interconnect, especially if you have the same manufacturer's brand throughtout your system. First the interconnect between the source and the preamp/integrated connection.
You'll need to replace each piece of equipment, BUT!!! Manufacturers have a "sound" they believe in. Rotel, from what I know, is not particularly 3 dimensional and you have, perhaps, aggravated it with cabling that is also on the lean side of neutral.
And finally, be sure your power cords do NOT touch the interconnects or run across the speaker cables. Keep them at least several inches away from each other, or you'll introduce hash into the upper midrange sound.
Good Luck!
