To my mind and experience as a player, as well as a recording musician, the sound of a room is an integral part of the sound of an instrument, especially so with strings, even more so with brass, but for reasons I don't understand much less so with woodwinds. I love CH woodwinds, I think the solo strings are great considering they are dry, but I have yet to hear a reverb unit, hardware or software, that can make a truly believable impression of a real hall - not to mention what playing in a real hall does to us players' imagination and the colours we produce, even if we're recording samples note by note. I love the control you get with well scripted dry libraries, and I have a lot of them, but if I really want to make a mockup sound as believable as possible, nothing beats a well recorded wet library in a great hall - there's no contest (except for woodwinds for some reason).
