I just got the CLA comps bundle recently for $199,and really like it,but having said that,a while ago I trialed the SSL bundle[too expensive at the time],but found I could replicate quite a few of the "included Waves presets",with the PC4K S-type Buss type comp,PC4K exp / gate,PC4K S-type channel comp,with the Gloss EQ[E or G type],and occasionally the PC76 U-type,and get incredibly close to some of the Waves SSL G or E type "channel strip module presets",and especially the singular SSL "mastering comp presets",with just the PC4K S-Type Buss compressor.
For ludicrous drum "hugeness" the Waves 76 blue/black,while better,is not a million times better,and the "dry/wet",on the PC76,is very handy,but the "all buttons mode"on the Waves is more dramatic,than the"infinity setting"on the Cakewalk PC76,but having them all,at an absolute tuppence-compared to the hardware,is where it's really exciting.
I don't think I would have bought the Waves comps individually,as the price is not justified,compared to how good the Cakewalk comps are,especially comparing the PC2A,to the CLA2A,but the Waves CLA3A is an interesting addition,and at basically $50 each,was too cool a deal to pass up.
