I wouldn't quite agree that this is the best reverb out there.
Have been playing with the RedLine demo for the past few days now, and I do agree that it is fantastic for the price. But after comparing to the Sonnox Reverb, I don't think its in the same league.
Sonnox offers much greater control, and sounds even lusher. The way in which the tails decay on Sonnox I think sounds nicer. I find, it tends to sit in a mix easier than the RedLine.
Don't get me wrong, RedLine is great for the price, and I will probably get it myself when the demo runs out because it is such a bargain. I think its a nice step up from the IK CSR Reverbs but not as good as Sonnox.
