Just a thought here - personal opinion kind of thing...haha
I'm not sure where I weigh in on the morality issue discussed earlier, sampling software vs sampling hardware...I've been thinking about this since the thread opened, I have no answer. Although in some cases I have no problem using Nebula and Acqua sampled hardware understanding there will be certain differences sometimes improvements sometimes just differences.
In the case of sonarworks, I purchased the software long before this thread but may have tried the nebula version to try it out. If I wanted to use it regularly I'm pretty sure I would have purchased the software because of workflow and because I can afford it. I can't afford the hardware that has been sampled and use the nebula or acqua versions instead. So you see how my moral compass works (I dont crack though)?
But in the case of sonarworks I have stopped using the software on every project. I do use it when I decide to switch headphones, for example: I'm out of state on a contract and have a set of HD600 Senn and Beyer DT 880's with me in the hotel. Those are 2 pretty contrasting choices for lows vs highs, etc. But when I switch headphones I'll bring up sonarworks for about 15-20 minutes, listen to some reference material on a track in the project, listen to the project, switch between sonarworks, hype sonarworks, un-hype sonarworks, bypass sonarworks...until I get a feel for the hype of the headphones. Then I turn off sonarworks and do my balancing thing with the project.
Anyway, that's one way to skin the cat, and entertain myself.
