If we are using cancellation techniques to quantify sound quality, then a difference of -90 dB out of a possible range of 144 isn’t all that great.

In fact, it’s not a “null.” It’s an attenuation brought on by the summing of signals with inverted polarity and/or out of phase. Some nulls might be only 90db, but that is still for all intents and purposes perfect. Or so?! Some dude once said “It can and should be quantified.” Out of respect for him, let’s quantify that as -144 dB. It can and should be quantified.a perfect 24bit null will be over 140db or so. enjoy the tools you like and stop bashing everything THAT YOU DONT LIKE. waves does a good job again BUT YOU seem to find something wrong with everything. Because of the subtleties, online testiomonials are unlikely to be worth particularly much. To do a proper A/B test of different models you need to know a lot about matching compression curves and when I do it I use spectragraphy to match saturation models too. In fact the plugins' knob values are double what the matching hardware values would be (which makes sense, since no one goes past noon on the hardware anyway). The UAD plugins and the UA hardware (both of which I own) match not in the slightest.

Note that comparing clockface settings on these plugins has no chance of matching. I'm reading people saying the UAD's gain structure is different than the Waves'.
