Hope you find what you need!

Stumbled upon them many moons ago, quite some nice stuff there.

Lots of great resources here. Thanks to all!

I've used TONE3000 with success in the past for when I was looking around for guitar cabinet IRs

Honestly I wouldn’t go for one huge pack, but if I had to pick a solid starting point I’d check out the Samplicity Bricasti M7 impulses.
They’re very well captured and cover a lot of usable spaces without being overwhelming.
Other than that, I’d still recommend building a small curated set over time instead of relying on a massive library

OpenAIR is still the gold standard for academic-quality captures in 2026 — great to see it mentioned earlier in the thread. For anyone who hasn't also checked them out, EchoThief (echothief.com) has over 100 real-world environments that lean more creative (bridges, caves, stairwells), and Voxengo (voxengo.com/impulses) has a smaller but very well-chosen set of classic spaces. All three are still actively maintained and free.
