User feedback & press reviews:

The HOFA IQ-Series EQ is one of the plugins that you do not want to lose if you had it in use once before.
The concept is ingenious ...
The dynamic function saved us a lot of work and allows completely new possibilities.
The equalizer is designed for the use on individual tracks as well as mastering.

Buenas Ideas

Because of its excellent sound quality, its clear interface and its low resource requirements the IQ-Series EQ was satisfying in our test across-the-board.
In particular the Dynamic Gain function makes this flexible equalizer an effective troubleshooter, which even enables drastic corrections, which are only implemented when necessary.

There’s just so much this single plugin can do. Apart from needing reverbs (which they make and I will write a review for soon) and delays (maybe we can convince them to make an IQ-Series Delay) you could mix and master entire projects with this single plugin and want for nothing. (...)
Since getting IQ-Series EQ, I’ve pretty much used it on every track that needs any frequency processing, (...) I hate overhyping anything but this is the most versatile EQ plugin I’ve used in a very long time.

I cannot say enough how excited I am about the HOFA IQ-Series EQ plugin.  I have been mixing and recording out of the box for decades and it has been challenging for me to make the transition to ITB mixing.  Mostly because there are a few indispensable tools that have only existed as rack mount devices.  For decades I have relied on the BSS 901 mkii Dynamic Equalizer as a sort of "secret weapon" for fixing problematic vocal recordings or harsh guitar sounds.  FINALLY!  HOFA has created a plug in that does everything the BSS did and much much more.  The extraordinarily tight Q settings, the wonderfully flexible shelf shapes and Being able to automate the controls makes IQ infinitely more useful for me.  Whether I am mixing in the computer or on my console, the HOFA IQ-Series EQ is my new secret weapon!!

The HOFA IQ-Series EQ really deserves the name "IQ". Its handling is absolutely intuive; by sweeping in the display you can quickly find the desired frequencies and the appropriate parameters and control them.
I got along with it as fast as with no other EQ.
The sound of the HOFA IQ-Series EQ is sophisticated, clear and pure.

I was almost dumbstruck ... Ingenious !!! A big plus, of course, is the variable window size.
The integrated analyser is marvelous! It is very useful even for inexperienced users, because you can see exactly where you need to use it. Especially for De-Essing and sibilance control this is very helpful.
Extremely interesting to me is the editing ability of the middle and side signal - wow!
Conclusion ... a high-end plug-in for an unbeatable price

IQ-Series EQ is SO transparent and most importantly, extremely flexible.
You guys nailed the sound and the interface as far as its intuitiveness and useability!
Well done again...
