(thanks @Avgatzeblouz for the following information)
Black EQ - Apparently a mixture of several devices (guesses : Neve 2068 and/or Neve 1077)
Black Comp - Again, could be a mixture, but smells a lot like a Neve 32264a or Neve 83065, with the addon of different attack times if it is the 32264a, and the lack of 3 release times (100ms and Auto 1&2)
- Black limiter : The limiter section of the 32264a or 83065, or a mixture of both.
Caribou Series - Elements from the Neve 8016 console (previously owned by Caribou ranch):

Offline Acqua Installation (PC Only, VST 2.4)
(credit to RJHollins and Will the Weirdo)
Note: This method is NOT officially supported by Acustica Audio. Whenever they update frameworks, there could be issues. Also, If you haven't enabled file name suffixes/extensions, you will need to. Follow this guide: https://www.thewindowsclub.com/show-file-extensions-in-windows
1. Copy the Acqua folder and associated files from your internet connected DAW's VST location (or the zipped files from your staging area) to your offline DAW's VST folder. You can find these locations in your DAW preferences or the Aquarius preferences Installation tab (gear button, upper right)
Typically these are a folder with [aqua name] so PINK3, for example. This folder contains .N2V files. Then the following files with [aquaname] before them:
2. Copy the NEBULAFRAMEWORKx64.aqu file from your internet connected C:\Windows\System32 to your offline DAW's Windows32 folder.
3. Copy the NEBULAFRAMEWORKx64.aqu file from your internet connected C:\Windows\System32 to your offline DAW's VST folder as well.
4. Copy all the files from the Acqua Staging area's FRAMEWORK/NEBULAFRAMEWORK folder to your offline Windows32 folder. Again, you can find the staging area on the Aquarius' Installation tab, which is inside preferences (gear icon at the upper right corner of the application).
5. Get your authorization from the AA site. Login and then click the stick figure person icon (third from right side) and then click licenses. Copy that .AUT file into the VST folder (same folder as the [aqua name].dll is located. So for the PINK3 plugin look for PINK3.dll . The authorization file should be PINK.aut and so on.
Core7: First released with Navy in October 2015. Major CPU and RAM usage enhancements. Zero latency plugins made possible.
Core8: First released with Amethyst and Pink in April 2016. Further computer performance enhancement and major compressor behavior progress. ShMod feature introduced with Pink2412.
Core9: First released with Sand in September 2016. Introduced Ultrasync technology for the equalizers (error minimization) along with internal routing controls. AAX performance enhancements. Since Titanium2's December 2016 release, compressors have Ultramatch technology. Ultramatch minimizes digital compression curves errors
Core10 (aka Core X): Cobalt was the first to officially receive the Core X engine. It provides faster compression timings for more accurate hardware emulation. A multi-input system. CPU savings with a blending algorithm that reduces the number of instances. The plug-in signal no longer exceeds +3 dB.
There's also a new hard clipping algorithm.
Core11: - Introduction of new Delay and Pre-delay modules.
- Implementation of High Efficiency Symmetric & Asymmetric Saturation Modeling (SASM), a high performance saturation algorithm/harmonic distortion modeling characterized by a significantly smaller number of digital artifacts.

• Upgraded SASM (Symmetric & Asymmetric Saturation Modeling) high performance saturation algorithm;
• Introduction of a new post-production sample de-noising tech for cleaner deconvolved impulses called STT (Super transient technology);
• Full compatibility with Client/Server architecture integrated by default in Acqua plugins;
• Engine optimization introducing a new highly efficient algorithm. This innovative technique is applied to all the deconvolved impulses for further de-noise processing and subsequent elimination of any incorrect low-level behavior (including the so-called "echo bug").
Core13: - Released November 2018 with TAUPE. New feature:
• VLA™ technology (Vector Loading Acceleration), which makes the response of the plugin much faster.
Core14: - Released August 2019 with NAVY2. The big new feature is the IRIS deep learning artificial intelligence technology. Other updates from Core13 include:
- AI allows you to replicate the actions of a mixing and mastering engineer and predict the settings he/she would make on the audio input of the plugin, imitating his/her style.
