I would like to get some wise opinions about buying either Altiverb6 (need some time to save up) or Voxengo Pristine Space (money is ready). I know their prices are much different, but I heard a lot of good feedbacks from Voxengo users.
PS is a lot cheaper, also because it does not come with any IRs. In my opinion the sound is equally good as Altiverb, if not better. If you need lots of IRs, save for Altiverb. If you want a reliable, no-nonsense convo plugin, get PS.
Waves IR1 is an excellent plugin, that includes a lot of IRs. But it is also quite expensive. A drawback of IR1 is that it has a fixed latency of 11 msec, whereas Pristine Space (my favorite) can have a lower latency. Pristine Space is much cheaper, but does not contain any IRs, although you can download some from www.voxengo.com.
Why not try the free demo from PS? You can also download some free IRs (also in True Stereo) from my website.
