A lot of amp sims have convolution engines for loading IRs, which is cool. But while researching the topic for a forthcoming book, I check out quite a few convolution engine options and was surprised at the wide variety in sound quality when using the same impulse. The ones included in amp sims generally weren't as good as the convolution processors designed for reverb. One of the best I've tested so far is MOTU's ProVerb, cab impulses sound really good through it.
So here's the question: there are a lot of third-party impulse responses out there. Do any of you have any favorites? I did find a site that has some pretty good free cab impulse responses

I don't have a super-pricey convolution reverb like the Altiverb...I wonder if it would sound even better, or whether you reach a point of diminishing returns.
