I got in some time with Ether Stat before the room got loud. First of all, I prefer the 007 to the 009 if that helps understand my preferences. The 007 and ES were actually somewhat similar. I preferred the ES for two reasons.
1. The sound stage width and depth was considerable better on ES. I was somewhat surprised at this. Possibly because I listened before the room got loud I was able to observe this difference more so. Once the room got noisy the cavernous sound stage of the ES seemed to get drowned out.
2. I prefer the mids on ES, especially on the BH that Justin brought. I mostly listen to vocal centric music, jazz and modern folk/Americana. I was hearing voices that were more naturally rendered with lot's of detail. Breathing between notes, chesty guttural notes from deep in the chest.
I still love the 007 and it remains my favorite production stat. I'm hoping that it can be improved on with something modern and at a friendly price point.
