Strangely enough I own the TC-60 and until recently owned virgo's. What you are describing is consistent with my experiences. The virgo's do not have as much body as the tc-60, especially if you have the tc-60's near a wall. One of the virgo's few flaws/characteristics is a somewhat lightweight presentation. It may just be the wrong speaker for you. You might give the proac or vandersteen line a listen. The vandersteens especially have a similar presentation.
To get more body out of the speaker, try a) putting the floor spikes on , b) put them about 6-8 inches from a wall and listen to them in more of a farfield setting (you will lose some of the magical imaging trick), and C) put a big solid state amp or powerhouse tube amp on them. I have never added a subwoofer, but that might help. Putting a big amp on them really does bring out their bass - it changes them quite a bit.
Even with these changes, you will never make the virgo a big voiced speaker. It is designed for low level detail, precision and speed at the sacrifice of instrument weight.
