Thanks all for the feedback on this topic, it's been interesting to see the comments and it appears many of us are in agreement on this topic to one extent or another.
It's hard to put into words what I hear when I listen to any of the recordings on CCH vs. what I hear in the Pipedreams recordings. Probably the best way I can describe it is the recordings on CCH regardless of the instrument or version of HW, all sound like they're in the same room, just with a varying degree of wetness applied. Whereas, in the Pipedreams recordings each acoustic has its own sound characteristic, you hear depth, you hear pipes sounding closer and further away depending on where they are located, you hear left and right and the nuances of the room, and for me anyways it paints a picture in my head of the room and what it might look like, these are the kind of things I don't hear in any of the CCH recordings and maybe that's the difference in a nutshell.
Funny, but in some of the Pipedreams recordings you get the occasional and unintended door door slamming in the background or someone coughing, and you can hear the distance and space in the recording again giving you an idea of the size of the acoustic. Don't get me wrong, not that I'm asking the sample set producers to put doors slamming and people coughing in the recordings to create more realism, but you get the idea.
