Sure we all love soundcloud cause it is fast and easy to share links, but Also I would be careful to judge a test done from Soundcloud the sound quality is not representative.
Hi Immersion, the possible audio degradation from sound cloud processing happened to all files so it does not invalidate the test or better put the "experience". This is definitely not scientific. Perhaps different sounds like piano or vocals would be more telling but I mostly use synths.
After some thought, well days of thinking my personal favorites are the R2, TSAR 1 & Lexicon Random Hall. Still need to track down which Reverb lends itself best for that "Lost in Space" sound.
Heres a long gearslutz thread where the designers of LexiconPCM native, Exponential Audio & Valhalla talk about their verbs. The link drops you in at page 14 where it starts to get interesting http://www.gearslutz.com/board/music-computers/717515-2012-best-reverb-plug-ins-until-now-14.html
