Mmmm thanks for the feedback guys. All interesting points.
I have to say that if you arrange an ensemble, then put a spot mic on one player and solo him/her, it will still sound like a solo player, and not like a less identifiable derivative of an ensemble, which no longer sounds like an individual player.
Whilst I accept the 'blending' argument to a point, I'm afraid I don't agree that individual players playing together no longer sound individual, if you listen to them on their own. They may not sound the same as an out and out solist, but the legato transitions, attacks, expressions etc. are still unmistakably those of an individual player. To my ear, the individual players in Dimension Strings, don't sound like authentic individual players, they sound like a kind of hybrid between a solo player and a distillation of part of an ensemble. This works great when they're all blended together, but is less effective if the ensemble is much smaller.
I'm by no means suggesting Dimension Strings is not a superb product, or that the ensemble sound it creates is not detailed and beautiful, simply that, for whatever reason, despite offering the flexibility of being able to isolate individual players, when it's broken down to much smaller parts, it is somewhat less effective.
All just my view of course.
All the best
