Since audio for near 100% nowadays is already digital from the source, DSP is the way to go for most people and EQ can greatly improve the audio when used to fine tune the tonal balance. EQ is great for room compensation in the bass, tiny tweaks, loudness compensation (Fletcher Munson) and high treble rejuvenation (compensate for your age related hearing loss). The company miniDSP is a popular option for the hardware. Dirac is a popular option for the DSP firmware. Usually these products provide a bypass mode to allow the music to route through it 100% unchanged, if you want to A/B compare. DSP EQ is used for precision calibration in modern active speakers and automotive audio.

@@shipsahoy1793 Yes, it's horseshit. Even a US$200,000 system can sound better with some EQ tweaking. I've been listening to numerous extremely expensive systems and always tell myself that Loudness compensation is such a big issue even more so for the most expensive system where your hearing will cause a narrow-band tonal balance at low volumes. If you want the best listening enjoyment, EQ is awesome. Of course, EQ can harm the audio fidelity when not used carefully. EQ tweaking should be done AFTER the system has been optimized acoustically (speaker placement, room treatment) to stay within a slim envelope of EQ.

The reason most preamps don't have bass and treble controls is that they are crude, a one size fits all solution with no adjustment other than gain with a fixed frequency response. DSP on the other hand is easily adjusted for center frequency, gain, Q, and filter type. Multiple digital filters can be used selectively and tailored to each systems needs.

When octave records records a track, that board is nothing but a huge equalizer. So, don't say that you are not a fan of eq. The recording engineer eqs the tracks as they are recorded. If your personal musical taste differs from that of the engineer, then using an equalizer is a natural choice for altering that signal more to your liking. I spent a significant part of my life playing live music, being in the studio and after my playing days, working as a live music engineer on the soundboard. Processing music of any kind is totally wrapped up in EQ. Audiophiles saying that tone controls of any kind is heresy is simply hubris.

Filters are always there regardless.. You can still achieve a transparent sound in spite of tone circuitry.

I'm a big fan of EQing. I prefer analog tone controls over digital. Sure, digital has more fine tuning (and I use it for that on one system, i use both!) but analog is limited to factory set shaping; but digital is also more prone to clipping, and analog tends to be much noisier. It's a pick your poison situation. That said, I've always found analog EQing to have the best tone and sound. I have analog bass controls that always (always!) go deeper and richer than any digital EQ could do, if I did it digitally it would clip and sound muddy and not nearly reach as deep. Digital is like a scalpel and is great for minor tweaking, especially for treble since you can cut specific frequencies; but for bass and mids analog is king.

I wish more DACs used the RME approach. Although I don't have an RME DAC (I'm happy with my SMSL VMV D1SE), the RME ADI-2 (in most recent form) really is several tools in one: DAC, Pre-Amp, Equalizer/loudness, and headphone amp. While some DACs have a pre-amp function and headphone output, those are afterthoughts and don't compare with a dedicated pre-amp or headphone amp, while on the RME they are said to be similar to fairly high quality separates. And no DAC (that I'm familiar with) has the EQ ability of RME. PLUS the more recent RME DACs have tone controls right on the remote control. Although the RME DAC with remote is fairly expensive at about $1300 US (with remote), when you add up all the features its quite a bargain.

So how do You see it and what is it today? For instance iFi Audio is all about analog volume knobs... Why is that when they can just get digital and go on like normal audio gear companies?

EQ could never be that important to me to fix any recording that needed it to then buy a $5K hardware version of a Pultec or other hardware version. But like he said, I would never do an A/D conversion just to use a plug-in. Happily, I left vinyl long ago, so EQ plug-ins (well designed ones) should always give me clean changes on all of my source material. Trouble is THE most common damage inflicted on my vintage 1960s/70s recordings was dynamic range compression-and usually applied globally and excessively in the mastering room. These "necessary" sonic crimes were legitimized to prevent overloads on AM radio and so record labels wouldn't get complaints about mistracking from consumers and their cheap vinyl players-or even SOTA turntables of the day. So now those with high res systems end up victimized because much of our favorite music that was so badly compressed sounds like shit because there's next to no dynamic range. And unless there's some kind of AI-driven solution years from now, there's no way to restore those lost dynamics.

Also the question is not a good one. Primary usage of EQ at end time is isophonic curve reproduction (Which normal people never be able to reproduce in the low end) regarding room speaker and device capabilities! Changing the sound to your taste is a bad idea as your certainly not as good as producer/artist! As soon as you have the right/most representation of the isophonic curve you can lower or boost the both end according your taste (which i also do not recommend) , that's why amplifier never get a mid range if done in the state of the art! If you use analog which i do recommend you need an eq behind/in front of each analog device specially for tape, to correct in case of need Very high end/record curve in case of low speed usage/no adjustable bias , on vinyl also to correct 16RPM in the very high end. In digital the source should not be modified as even if bad quality reproduction, there is no issue regarding bandwidth! In most case unless your on dsd 256/512 it sound bad because it's bad nothing more, adding mathematical (digital) correction to something bad = something bader!

To finish if you need correction after isophonic alignment and you will (even if not recommended) there are two main reasons: - 80% of mastered sound is very poor in the mid/high range resulting in a +5/+25db in the low range so you need the lower the low end quite all the time. The good reference are old mastering not new! it's easy to hear when you're aligned! Specially digital which is furiously and unnaturally high in the 20/60Hz range! Why because loudness war and mass quality devices heavy reduction in the low end and for digital unatural low end bandwidth behavior well known in electronic music, etc, ask JMJ he well fought for this problem unfortunately still active! - You have hears disabilities! In that case to have worked with that kind of people, you need to switch to analog, digital distortion are so huge that it's painful for these people. One of my friend terminated with only piano or bass digital sound! Unless you can afford dsd 512 files, better go to analog less prone to distortion in the mid/high range. It's better to 1-4% distortion on all the bandwidth instead of 1-100% with digital (even filtered at dac stage) for these people! And no having a dac with 0.000000000000001% thd won't solve the issue! Again digital full of technical stupidity dreams...
