I bought both Equium and Firium. Both are fantastic EQs. I use Equim in both Logic and Nuendo. None of the supplied EQs come close to these. I find them to be more open in the top end than most EQs. Equim does not have much color, but that's good for me. The controls are just great. It's very easy to dial in the sound I'm looking for quickly. I went on a long search for a great "bread and butter" EQ. Equim is the best that I found and the price is reasonable.

What to say about Eqium? Hmm, what not to say? It allows for an unlimited number of bands, all with adjustable Q settings, has two types of low and high shelves each, as well as low/high/band-pass filters, as well of course as the stock parametric filters, and don't forget about those notch and the two types of harmonic filters (hit the down button under the filter types to see those). So can you have more flexibility in an EQ? I think not. In fact, I can't think of any other EQ that approaches Eqium in terms of flexibility. Ok, but that doesn't mean a thing unless the EQ itself actually sounds good, and Eqium sounds fantastic. As already noted, it is highly transparent. This is not a character EQ by any means, which makes it the perfect all rounder. It has a fantastic low end, extremely well defined mids, as well as fantastic smooth and open sounding highs. Other EQs at similar settings, simply do not hold up in as many scenarios anywhere near as well as Eqium does. The one thing Eqium could use, that it doesn't feature is a frequency analyzer built into the GUI, but guess what? Elemental Audio has a free plug-in that does this called Inspector, and while not being as convenient as having it within Eqium's GUI itself, it's free. Oh, did I mention that Eqium is light on the CPU as well? This is the best all round native (non-linear) VST EQ on the market IMO, and by far. Download the demo, then take out your credit card and place an order, because that will be exactly your response upon using Eqium for a few minutes.
