Well! now I can say that the Neve 8816 is not taking out some low mid info!
I maybe prefer B and found on B this:
Basicly is just a very tiny difference to me.....that is more a perception, I feel a super, super light warmth and a super tiny bit of depth and a little bass boost...yes I think B reacts better in certain parts like in the bridge where I feel a bit more cohesion ..like a light compression.
Soundwise I think the difference is not vconsiderable at all and you have to really close your eyes and really " try to hear and find " those tiny differences...I think is so hard to find the differences that from one day to another you will not know which one is Aor B.
Anyway...I think soundwise is not worth it the $3000 ticket, but if you want great Hardware integration, a good monitor section with width control and AUX..and other cool features...maybe is not so bad...and I am sure many would like it...also you may have a Neve unit that processes all your sounds!! many find this very attractive!
I am just here trying to judge only the sound,,,,,now, I also think may be interesting how this piece influence your mixing decitions..and maybe there is where is all about....so hard to know without the unit for a few days....
This so is not my song cup of tea(style) but I have to admit was cool and refreshing and I really like the feel of the vocals!

very good Vato!
Vato what was your vocal chain in the recording and in the mixi?
Thanks!! I see you are really trying to help here and give all the best info for the Slutz interested in the Neve 8816!
