Bapu and Small,
Glad you both got in on it too before the discount got removed!
Zo, you should download the demos of them.
PCM is the same algorithm used in the acclaimed PCM series Hardware Reverbs.
They are all quite beautiful and lush sounding reverbs, which is what Lexicon is noted for.
Definitely sound more like "spaces" then "reverbs".
Closest thing I found was Redline Reverb, which is an awesome reverb, but not as "full" sounding
as the Lexicons (but not by much, and in many cases it fit better into a mix then LXP did - IMHO)
