Acon Digital Defilter

I haven't used either of those plugins, but I own Verberate and the restoration suite. Both are excellent and represent a great value. The restoration suite works really well and it seems to be the cheapest noise removal software. Verberate is an amazing reverb. It sounds clear and uncoloered even though it doesn't use impulse responses. I use it whenever I need something that sounds like a real space(I use vallhalla vintage verb or room my other needs). I've found them to also be responsive with their support. Good company IMO. I don't feel I need either of the products above right now, but I keep Acon on my radar because they seems to come up with great products that aren't crazy expensive.
