Valhalla is good, Relab LX480 is better
..'See you and raise ..one PCM bundle
I've used several plugins and hardware (Still digital) Reverbs
The least offensive I found so far was the UAD EMT 140 plate. None of them I would say sound great though. I've found room mics and/or delay to be far more pleasing to hear over artificial reverbs almost every time
YMMV
I almost exclusively use SIR with my vast collection of impulses.
I have impulses of every major reverb unit ever made along with real spaces, unconventional spaces, and effects. I also have impulses of classic gear circuits being driven for colouration although I don't use them much.
Cheers
I absolutely love my PCM 90 hardware. I don't use it as much as I used to because there's a bug in Cubase where it doesn't remember the hardware routing from session to session which is a pain in my ass.Best (IMO) reverb plug-ins that I've found/use are the lexicon pcm series. Since using them there is no need to look elsewhere.
