I highly recommend Reaxis. Enormously versatile, capable of recreating easily recognizable legendary tones as well as dialing your own signature sound.
Upgrade, that's gonna last for ... how many? Six months? One year? That is, before the next major (paid) upgrade comes out. Still not convinced with the workflow.
Anyway, the best price I've found so far:

Best Service have boosted the offer with a free product of your choice, which makes TT upgrades look a bit more attractive. Not sure if the same offer applies to other products, though.
Any idea how long this is going to last? Literally a week? I've been eyeing their Speaker Shaper plugin, hoping to get a better deal. $49 is acceptable but not very inspiring.
Thank you! This software looks awesome. I just don't want to mess with myriads of IRs and that's the main reason why I want this plugin. Other than that, I'm all set with cab-sims. 😊
More often than not it boils down to proper IRs. Amp-sims of major developers are in the ballpark. PA IRs never really impressed me. Some are usable at best, bust most of them don't deserve any attention. I suggest to try whatever amp-sims you have with other IRs first, before you decide to invest in a new toy plugin.
I've upgraded form K11 to K14U just yesterday and don't regret it. Quite a few mind blowing libraries that are new for me and on top of that they also provide Ozone Standard 10. ATM, I'm trying to decide whether AR Drummers and Studio Drummer are worthy of SSD space. 😁
