I swear, the only bwl's I can bear to put on the 2-buss are Izotope, Elephant, Loudmax, GClip or my AD.
Everything else I've heard, including Sonnox, Waves L2/3 & Sonalksis and gang, just f*cks the sound up far too much, even at 96k. You might be able to get a louder master with it - if the tonal balance is off (!), but if that's on point then... I used to use the Sonnox, until the artefacts became so abundantly obvious that I just couldn't do it anymore. Xenon, robs the transients blind if pushed too much, but sounds extremely transparent for the odd peak here n there. YMMV, of course
