Ok simple thing.
I made this Cello Line in Appassionata Strings (Panned Hard Right):
Then I used several high end Reverbs to this dry line. In the convolution reverbs I used the Sydney Opera House Impulse at 12m. I used Hall algorithms for the rest Reverbs
Simply CHOOSE which one sounds best for you and why I will reveal what reverbs I used in each version later.
Also leave comments about the ones you did not prefer. Remember this is a BLIND test so I wont reveal to anyone what reverbs I used in each situation.
Reverbs I used (not in the correct order):
Altiverb, Waves IR-1, Arts Acoustic Reverb, IK Multimedia Classik Studio Reverb, Oxford Reverb, Lexicon Pantheon.
You can suggest other reverbs for me to include in a future blind test.
I did my best to finetune the non convolution reverbs but it always has its flaws.
