Interesting that yet another plug-in that is talked about wildly in the KVR Effects forum has zero reviews.
I'll just make it simple. EQuality sounds great, it's flexible and it's easy to use. It's pretty much every thing you could ask for in a software equalizer. You won't be disappointed just try it!
Oh...I have to use at least 500 characters? OK...here goes:
EQuality features 5 EQ types. "Digital" to analog to Linear Phase options are available. Variable slope (6dB to 48 dB) high and low pass filters. Low shelf, 4 parametric, and a high shelf filter as well.
The spectrum analyzer makes using this a breeze. There are tons of settings to change things up including K-system metering. If you're looking for a clean EQ this is a great option. Combine this with a nice "character EQ" plug-in for boosts and you're good to go.
The reason I gave the plug-in an 8 is because the minimum and analog phase modes aren't analog-spunding enough for my tastes. That and I wish the GUI was larger/expandable to accomodate big resolutions. Spectrum analyzers are easier to use with larger windowed plug-ins. Other than that I love this software!
The dev has stated in an interview that he has intentionally NOT modelled any saturation characteristics of analogue hardware, which is probably what you mean by "not analogue enough". That shouldn't reflect on the quality, however, so marking it down for that doesn't seem right. But it's good that it finally got a review here. ;)
"EQuality has been designed to be the perfect EQ to let your mixdowns shine. Something for every track of your session. For it to sound at least as good as any high-end console or rack gear,..."
And then your product doesn't have saturation as an option I have to mark it down. It's not a "perfect" equalizer without those options, IMHO. So I deducted 1 point for that and another for the GUI being small. This makes using the spectrum analyzer a little harder. Examples of better implementations are Fabfilter Pro-Q and Waves H-EQ.
In the case of Pro-Q the analyzer takes up the width of the plug-in window. Equality's analyzer feels cramped in comparison.
In my view, no saturation and/or noise modelling actually gives you the flexibility of choice, so you can use what you want before or after the EQuality for that. ;) Speaking of analogue modelling, the great thing about EQuality is that it does try to emulate the analogue phase behaviour, not just frequency curves. However, it doesn't introduce any non-linearities as far as I know. Phase always jumps up-down a little in analogue EQ, as well as the frequency curves.
