Well, I have tried it and …like it a lot!
I am not going to elaborate but will simply say music is more enjoyable, and sounds are more pure. Go figure.
I have Parallelize off which sound better to me but makes the CPU core work alot more. My processing speed is about x2, significantly less than previously.
I too have noticed a drop in dB and agree it is way more than would result from lowering the noise floor. BTW, noise floor is not noise you can usually hear, but the very high freq interference impacts electronic in a way that affects SQ.
Having said that, I can now hear more hiss in silent sections of more tracks, perhaps on the recordings, perhaps due to the sample conversions, or both.
It am yet to try different modulator filters, current using 5th order CLANS.
