I'm a big spring fan and it's my main mix reverb for years now. I used to use a stereo Orban and Furman spring before moving digital. The Spirit Reverb was one of the best recreations I've tried and which gets the subtle overtones and dimension you'd expect in a real spring.
The downside is that it hasn't been updated for a few years. The last supported Mac version is 10.13 and it no longer works on 10.15. Support did answer me but none of their suggestions solved it. Maybe the Windows support is better. If you are on an older version of Mac OS or Windows, definitely check it out. If you are staying up to date on Mac OS, some of the better options like Space Designer (Logic convolution) and Amazing Stereo Spring (Ableton convolution) will be a worthy replacement.
This spring reverb emulation is like no others, highly inspiring to me.
Rather than trying to emulated spring reverbs accurately, that still seems to be an unreached challenge in the virtual world at the present time to some expert's judgement, the folks in Aegan music managed to capture some of the typical, coloured aspects of these vintage reverbs and gave to the users something highly tweakable, leaving the possibility to modify the most inspiring aspects of spring effects (rather than properly called "reverb") that no real spring reverb would be able to offer.
So there is here a wide palette of different colors ans characters in these emulated springs that IMO compensate very honourably the lack of accuracy that some might feel...and i'm not one of them.
I own already both Overloud Springage and PSP Springbox, both are very good sounding spring emulation in themselves, but this one IMO, gives the best set of parameters and flexibility for innovative creativity.
really excellent and among the best sounding but more that that, the most flexible in relevant manners for creative purposes..and that makes a significant difference for me .
... also considering the very reasonable price. among the three mentioned in this review, it's the cheaper of them for a same level of quality .
