Well, running the risk of adding fuel to a fire, I happened to be sitting in front of an SSL this morning and so threw together a quick comparison. For your A/B'ing pleasure:
Console comparison (it's about 60 MB)
This is three mixdowns of a project I'm working on this morning. One is ITB no console, one is ITB with Cakes console emulator in SSL mode on 16 bus channels, the last is those same 16 busses out through the SSL (signal chain is RME MADI card -> Antelope converter -> SSL -> back to converters to record). My SSL isn't large format, it's just the one in the pic below with the comp and EQ disengaged...the coffee cup is in the pic because it's early and should have no impact on the sound
I am mixing through the SSL so that may have some impact. Oh, and I don't have Slate VCC so I can't include that as a comparison point...I would have downloaded a demo but I'm doing actual work this morning and...well...honestly, don't care that much
