Hi.
 
I own both McDSP FilterBank/MC2000 and Waves SSL 4000 Collection bundle. All these plug-ins sounds great, and it’s up to me (and every other recording/mixing engineer) to pick the best tool for every task at hand. Although I’m very impressed with Waves SSL I will continue to use eq/dynamics from McDSP/Eventide/Digidesign/Sony and others. That’s because they are good-sounding plug-ins, and I know them very well.
 
Furthermore, I don’t think it’s fair to compare AC1 to the G-Master Buss Compressor. McDSP’s Analog Channel contains two plug-ins which set out to emulate analog channels and analog tape machines. The G-Master Buss Compressor is based on one very famous and great-sounding console with optional analog emulation. It’s a kick-ass compressor…and then some. You know…the ol’ apples vs apples…
 
However, I do see your point, GORILLA. Waves SSL 4000 Collection bundle sounds great, looks terrific and I feel good using it. I actually get inspired by this bundle, and the best mixes are still yet to come. That would be when I know these plug-ins as well as the others I own.
 
Cheers.
