It's good; not the best SACD in my collection, but it's one of my favorite albums, so it's fun to hear in this new configuration. The only negative so far is that perhaps because the sounds are now spread out more, I can hear sample edits now that I did not on the original release. That can be distracting (actually, at first, I thought the clipping sounds I heard were the speakers themselves having fits... on closer inspection, it's just sample points).
Some of the choices TR made in this mix I have to get used to - the balance of the arrangement has shifted, and while overall I'm happy with it, some of it is jarring and I don't know how much I care for all of the changes. Repeated listenings will help me make that kind of determination.
Worth getting? Sure. Perfect? Probably not.
BTW, anyone know if he's mixing the new NIN album for both standard and 5.1 surround?
