Lindell Audio EQ825 captures one of the rarest and most sought-after mastering EQs ever built. Few pros have ever touched one, yet its retro, technicolored lines are instantly recognizable. If you don't have $20k to spare for an original, this plugin truly does the pinnacle of tube mastering EQs justice. Its presence, warmth, and pristine tone all sum to sonic gold.

The unicorn of inductor EQs
The original hardware was built by an ingenious group of esoteric audiophiles, who cherry-picked the best analog components from a multitude of manufacturers. Lindell Audio are the first to faithfully capture its five iconic EQ bands with their incredibly customized filter networks – all those inductors, resistors and capacitors. Hear them working their magic in the airy highs, tight lows, and midrange presence they add to drums, and the smooth top-end and enhanced "air" they bring to vocals.

Smooth tubes and high-headroom transformers
The extraordinary sonic profile of those special EQ curves is further enhanced by the unit's premium tubes and transformers. This clever combination of components brings sweetness, depth and punch to your mix bus. It also delivers extraordinarily high headroom. Want even more character from those tubes? Just crank the Variable THD control.

The high point of analog mastering EQs
Lindell Audio has resurrected one of the few A-Tier passive tube EQs built around the turn of the century. This legacy is also a big part of its special sonic profile. Its construction combined classic topologies with modern engineering approaches. The result is a premium analog tone with a significantly lower noise floor and greater clarity. This really counts during mastering where all those imperfections are applied across the mix and really add up. This unprecedented analog clarity makes the EQ825 plugin perfect for the most demanding applications, including orchestral arrangements and final mastering.

A few tweaks from perfection
Lindell has faithfully replicated the original hardware, revered to this day. Versions with stepped gains are known by some as the EQ "cheat control". Bands are expertly configured to offer musically beautiful EQ combinations. Lindell has modeled the continuous gain controls on one of the earliest units for greater flexibility. You can easily dial in those cult combinations by selecting the whole values – it just takes a few turns to hear something special. A valuable addition is the new spectrum analyzer, so now users who like visual feedback can make the most of its coveted curves while EQing.

More than a collector’s item
New features expand the utility and creative potential of the hardware's special sound. These include options for Mid/Side processing, Mono Maker, and up to 16x oversampling. Bring a new dimension to the EQ’s famously tight and punchy low end with the Octave Filler. This function adds a lower octave into the signal. It sounds amazing on kicks, 808s, toms, and bass.

The Lurssen mastering EQ by IK multimedia is honestly top tier wondering how this will compare to it

Lindell sounds most like an analog EQ to me, more body & sweeter tops. I tested it using Plugin Doctor to match settings, IK has extra high freq harmonics & sounds a bit digital, I don't like the 6-8k area on IK. The IK doesn't do proportional EQ properly either. I also tested AA Erin & it sounds a little lean too, not too many harmonics. Finally I tested ProQ4, it took a while to match the curves, it doesn't do proportional filters, also no inductors, I got it to sound good but not the same, still sounded digital even with the different saturation modes.

Id have to disagree, I think n the Lindell sounds β€œclunky” and can’t be pushed the way the Lurssen Mastering EQ can be pushed, I do like the graphical EQ though with the Lindell nice touch, the IK version sounds more musical to me

many developers are doing this because of the systems they are using to do support their users with. It doesn't mean they won't work with others.

But the distance between what something will work on compared to their "minimum" has really gotten further apart. It makes it look like they are just guessing. iZotope can be bad too.

Fun fact: Plugin Alliance has always been running under ARM too, even old Intel stuff from back in 2014 - it's simply a great dev (unfortunately with an ass business model...)

Plugin Alliance is now Native Instruments owned, I think there's some input there. The only PA made plugins are the Brainworx coded ones, the rest are coded by the individual developer's.

The octave filter is a narrow filter in the lows, it has a lot of boost, at least 10dB at 50%.

Yes, but it starts aliasing REALLY badly. You have to be very careful pushing this plugin...

Maybe try boosting the octave filler quite hard on a subby kickdrum. Might be a bug in the plugin.

it's not bad, matching curves Erin by Acustica Audio preserves the transient a bit better + it has preamp section on/off, the ear compressor (very good) and other stuff also this suffer from aliasing (how can you manage to introduce aliasing in an eq in 2025?!) while Acustica doesn't, haven't tried IK Multimedia since I can't be bothered to hold all the bundle when I only care of few plugins. Everytime I wish some new tools allows me to delete some acustica from my drive, saving me space and cpu... and pretty much every time this doesn't happen. Thanks HCiSO, Mac institution for Plugin Alliance.

So, you say that this isn't really really good. Ok. I'll pass then. I use the Kiive Audio Focusrite EQ, Vertigo VSE-4 (when I want to distort bands) and Massive Passive UAD or Pulsar (haven't tried this one yet) and the Sontec EQ from MBS.
  Member 10.04.2025 77

It depends... Each analog eq does different curves but when you have a mastering eq like sontec or maselec or gml you pretty much can do any curve. We have so many goddamn eqs these days it's embarassing. You may find you like to use and dial in an EAR eq for a given circumstance, and in that case you might want to pick up the best one, or you can deal with the little downsides of this one and save of drive space and resources. Overall it's pretty tough for algorithmic plugins to compete with sampled machines, but on mono material (recorded instruments for example), the difference is trivial, imaging and depth becomes more of a problem for algorithmic plugins on stereo material. In that case better pick up good stuff or use outboard.

DrDexter, you seem to know what you are talking about, can i ask have you tried thEQorange by MAAT, its seems pretty good to my ear, thats what i use if i need to tweak the master. thoughts please

I tried it long ago when I wasn't yet as knowledgeable in the sound engineering side of things and when I didn't have yet such expensive listening (also I can't be bothered with such price). Here's the thing about digital eqs: it depends on what you want to do, you want to add stuff or remove stuff? Are you live and need 0 latency or in mix and mastering? You talk about Master... Does phase shift in a given situation affect the sound positively or negatively? So you need to check if for a given adjustment minimum phase or linear phase is best (usually the correct one sounds fuller, because you don't have micro cancellations and you're adding or subtracting signal correctly), eqorange is a porting of an old linear eq. How does a given linear eq move act on transients? And if you add/remove, what you really want to add or remove? For example some digital eqs respect transients better, but when you want to remove or boost maybe sometimes you want to remove boominess/sustain, or add such sustain, and maybe sometimes you want to act on too much/too little punchy transient and with what balance you want to act on both? That's when something like SplitEQ is very helpful, although unfortunately is only minimum phase. Pro-Q is a good workhorse, is there something else 0.something% better in a given situation? perhaps, but how much time do you have to copy all settings across 7 digital eqs and do a/b? If you like it on your use and you can't replicate the results, then keep using it! I haven't checked if the eqorange has any negative technical errors in the dsp coding side of things, but if someone like Bob Katz endorses it, then I'd sleep pretty peacefully :)

I own & tested all 3 825 EQ's in PI Dr, I think this is the most hardware sounding box, the most musical. I have all those other EQ's too except UAD MP ( I owned the HW & got bored with it. I also own MAAT Blue which can emulate the curves of any EQ, as well as Equilibrium & Cenozoix all true mastering quality but totally transparent. Sometimes its better to pick your own colour, which you couldn't do with analog.

Orange is Linear Phase which suffers from pre ringing, LP EQ isn't as widely used as people think, when it works it's great but it doesn't always work in every situation. All analog EQ's have phase shift, it is part of their sound & it has been said that is the main difference in sound between different EQ's.
  Member 10.04.2025 77

Pre-ringing happens only in some really extreme settings these days, I honestly was never able to do something to a signal that caused pre-ringing in a practical setting, often I find phase shift much more detrimental to the signal, but as you said and as I suggested as well, it's situational.
