not that my responses even belong alongside or can add anything... but when you say "equal to" (bar none)... well no... because with individual irs you can in theory do a lot more in terms of panning, setting vol, etc... but the mix from mfg like mr york are > in the sense that I would almost always assume they have better ears, and are better at mixing irs, are listening on much better equipment and probably have even been reviewed by more than one person. In that sense I would say the professional mixes are almost always better in quality imho.
all that said...
@York Audio - really love your new twin verb pack!! as usual there is some great attention to detail in the high end that I'm not hearing in the rest of my twin ir collection. I have only played with it a bit, but really like it and just wanted to say.
If anyone is listening and looking for a very 'vintage correct' sounding twin ir... really hits the spot.
