Equalizer in a Hi Fi system
Just curious to hear everyone’s opinions on using an equalizer in a high end hi fi system. Was at work tonight and killing time and came across a Schitt Loki max $1500 Equalizer with some very good reviews. What are some of the pros / Benefits and cons in using one. Just curious. BTW. I’m talking about a top of the line. Hi end equalizer. Mostly to calm some high frequencies and some bad recordings.

@milpai Thanks, that's a great tip. Didn't know that. But it does make sense. Many times the official Help within a program is lacking, and I just ask the same technical question in Google and get the answer I need. Very often there's a Youtube video showing me how to use the feature I want! |
@mirolab , One more trick you can do, if you know a few words in a thread's heading. Go to google and type like this: "equaliser in a hifi system" site:audiogon.com I purposely made the spelling mistake in "equalizer". But Google got me THIS thread as the FIRST hit. That last part is very important. "site:" followed by the specific site you want to search. You might be aware of this, but I thought this might help others. |
So is Audiogon's search good for ANYTHING?? I really like this thread, purely about equalizers, but if I search discussions for "equalizer" it doesn't find it.... at all! Even if I type all the words of the exact title "Equalizer in a HiFi system" it does not find it. Oops... you see my tiny mistake? I missed just ONE tiny space in the title and it did not find this thread. This is the exact opposite of computers helping us! |
@jtcf , I am so happy the API has worked out so well for you. Furthermore, am happy for the others who have dared to try pro analog EQ or MQ112, branching out from the Schiit products, and being richly rewarded! This has been an illuminating forum for many. I am so glad. 😊🎶 |
@ditusa that's a lot of knobs to adjust:-) That's not a criticism. Too many for me as a newbie though!Concerning noisy opamps - I can only speak from my limited experience. My API is dead silent.Nary a click or hiss.There's no issue having it stacked on my dac or preamp either. I know that Schiit admits to experiencing noise issues with the Lokius and recommends to keep it isolated from other components. |
I use a White Instruments Inc EQ 4100 10 Band/Channel, very transparent see here. Mike |
No audio pro would attempt to set up a sound system in a venue without using EQ. Rooms are different and getting decent response in any room usually requires a bit of EQ. I use the DSP in Roon and a pro audio 32 band equalizer for other sources that costs far less than that Loki and has more control. The idea of opamps sounding bad is ludicrous. The recordings you listen to went through dozens if not hundreds of them unless you are listening to nothing but 50+ year old vinyl. |
Op amps are bad as a blanket statement is NOT TRUE. My Charter Oak has op amps in circuit and is the best pro studio EQ hardware I’ve ever had the pleasure of hearing in my home. And I’ve heard several. It’s all in the implementation and the quality of parts used. Like the old saying goes, the devil’s in the details. 😊🎶 |
@vacountryboy the only issue is when an instrument or vocal is emanating from only from the side where your hearing loss is. If there's no or little information from that speaker to begin with turning the balance towards that side or the levels up wouldn't help.Mono recordings would work of course. I don't regret buying the Lokius.It was always meant to be temporary, an inexpensive way to experiment.I kept it past the return period to continue trying balanced cables and while considering the next step to a pro model. If the API was available in black or silver it would be unobtrusive in a home system. It's the same standard width as most components at 19" and the "ears" aren't obvious. It's nowhere near as attractive as the MacIntosh EQ though.😍 |
I scheduled a hearing test, at 75, I’m sure they will find something, if nothing else I am guessing one ear slightly different than the other. Any equalizer that is single band is going to make same adjustments for both speakers. I advocate Dual Band (L&R separate adjustments), and 31 bands of adjustment 6.8.10.21. 31 bands gives you more precision for both your space and your hearing with no aids in, or aids in. 31 bands gives individual control of 1/3 octaves I bought/returned one that had no detents at zero position of each slider. I chose DBX 2231 /dual Channel 31 Band with Detents. One advantage is that it is 3U 5-1/4" high, thus the sliders are ’taller’, more precision adjusting the sliders. I went for Chinese Made Clone (identical, dbx are made in Malaysia, dbx manual in the box). They are a metal box with a power supply, printed circuit boards, identical controls, i.e. same parts.

I added a McIntosh MQ112 to my system last night. Between a Benchmark HPA4 and AHB2. So far, so good. The intention is to use it more or less like a loudness button. I had a Dangerous Music BAX EQ for a few weeks, but one of the switches developed a problem. (Returned to Sweetwater for refund.) Apart from that, I can recommend the D. M. BAX EQ, especially for its separate controls for L and R channels. And the fact that (apart from the low and high cut filters), it is a shelving EQ. So why not try another D. M.? Fair question. I don't have a great answer. I did try an SPL Vitalizer after the D. M. Lots of fun. Might be worth a try. At low volumes, worries about "high fidelity" seem a bit ridiculous to me, if pushed too far. The SPL has a hard bypass. I don't recall if the D. M. does and I haven't experimented yet with whether signal passes through the McIntosh with it powered off. Again, though, I have no complaints yet about the MQ 112. It was between it and an API 5500. (Allegedly hard/true bypass also.) Could have gone either way. And I might still. |
vacountryboy It's very simple. Just take a look at your audiogram printout. It will show what frequencies you are deficient in on each ear as well as the decibel loss.Then just find an equalizer that covers those frequencies and boost those frequencies by the same number of decibels to match the deficiencies on the printout, while leaving the remaining bands centered (not boosted or cut).

@minorl I went to Skyfi audio and purchased this a few months ago. I told him what I had in my audio system. My system is ARC Ref 750s mono blocks. ARC Ref 6SE. ARC Ref CD9. B&W Matrix 800s. Mac MQ112 eq. Straightwire Crescendo tri wired speaker cables and XLR interconnects. 4 Audioquest Dragon PCs. 2) HC and 2 Source. This Mac MQ 112 is phenomenal. It’s just exactly what I needed to tame the high frequencies and not so good cd recording. I can’t recommend this MQ 112 enough. It’s an awesome unit that also looks beautiful with all my ARC gear. That was also very important to me as I did not want anything industrial looking. With or without mounting brackets. |
I was/am interested in the McIntosh MQ112 equalizer. I saw the Skifiaudio video on this unit and one thing that struck me was internally, the unit incorporates op-amps. I was looking for a fully discrete unit without op-amps. I'm not sure about incorporating op-amps into my system. According to the video interview, the unit was really intended for McIntosh owners that have older systems without equalizers or tone controls. I'm still thinking about this one. enjoy |
For sure you are right !
I will trust more analog EQ too than this panels behind my ears...These panels are like my wood foldable screen, a device i used in my room , i could not use it without a balance between absorption-reflection-and diffusion in the room and on the foldable screen... ... And hearing aids use digital EQ for creating tailor made hearing aids for specific frequencies loss... Psychoacoustics rule audio in any form...
|
I would like the opinion of those using EQs on whether an EQ can assist with hearing differences between left and right ears.. in my case the left is more deficient than the right that shows minimal age-related decline. I have seen elsewhere that this might be a better solution than a single hearing aide. Besides needing to differentially apply EQ to left and right, I tend to switch from listening with speakers in front for critical listening to speakers behind me as I work. Therefore, I need a solution that can quickly be set to reverse (mirrored) application. Any advice/guidance would be most appreciated! |
Understood. Thanks. Room correct to flat. Then impose target curves to tonal preference. The second part for me is the hearing is believing part. If I’m gonna tonally adjust in the digital domain, I’ve gotta hear that it is as 3D and saturated sounding, and as musical, as analog. Gotta hear a DEQX in action. Let me know where I can. You know how to reach me. |
@tlcocks Not entirely true TL. Room control is going to change amplitude response across the entire audio band and it will give you a flat system to start with. All the Room Control units I know of also allow users to control amplitude just like an equalizer or by using target curves. Your preference settings will be different after room control is set up. |
“tlcocks No offense to you or anyone but I gave Schitt a try by buying 3 components for a guest room and all 3 had issues of some sort and had to return them all. Horrible customer service and subpar product in my opinion, and yes I am talking about their so-called top of the line stuff. The saying you get what you pay for definitely applies to Schiit based on my own personal experience with them. As far as well regarded, as you mentioned, definitely not to me. Perhaps as paper weights. To anyone reading this, if you enjoy and are happy with your Schitt products, congratulations and enjoy, just don't try to convince me, because I won't even respond. They have made my permanent "never buy again list", together with other companies which I will not mention for the sake of not initiating a back-and-forth and time-consuming discussion in vain. Peace...” Amen, sister!! Offense?? Are you kidding me?! @ellajeanelle , you are singing to the choir! I’ve been saying this the whole thread. You just say it better! Schitt is sh*t!

“Thanks to both of you for the info on the EQ. I am definitely going to do more serious research into the API equalizers. It may sound picky, and you can call it girl stuff, but I want them in black and no rack mount ears, or removable ears. Only one of them will be going on a rack, the others not. I like everything to match! “

@mbmi I have had the brand new Mac MQ112 now for about 4 months or so. And all I can tell you it’s a fantastic EQ. And it looks awesome with my ARC gear. Another reason I didn’t want to go with the others mentioned is that they looked very industrial to me also. That alone was a big reason not to buy them. U will be extremely happy with the MQ112. 👍 |

mirolab Thank you, someone recommended that one to me. Although I know they make good stuff because I had a few components long ago I am no longer into McIntosh. I know that their newer stuff is more neutral as opposed to their older warmer sound, but their overall looks and voicing are just not my preference. |
@ellajeanelle For looks AND performance, it would be hard to beat the new McIntosh MQ112. |

@jtcf I'm assuming you are new to API eq. API EQ's have long been a standard in studios. The most famous model 550 has stepped controls. This is both sonically superior, AND more easily & accurately recalled at a later time. This new API eq is half the price, and uses pots instead of stepped controls. I'd prefer the continuous pots anyway. So happy to hear you are enjoying it! |
@ellajeanelle there is absolutely no hiss.In fact there is not even an audible click when switching to bypass or back again. This is with very sensitive Zu speakers.I'm using it between the dac and pre. When reading what other users think of the SR24 some are not comfortable with the knobs that don't click into place - they move smoothly and freely. So you can't easily repeat a setting without writing it down.To me it's a good thing to be able to find a 'perfect' setting just beyond one of the marked dots rather than forced to choose one or the other. I don't know enough about circuitry to know if freely moving moving controls are partially responsible for no audible noise or it's just the choices made in the design of the output circuitry. Changing the subject for a minute back to what it does in my system for a bad recording..... James Gang Live in Concert (1971).Amps cranked up to 11 to achieve a big sound with only the three guys. Joe's amp I would describe as literally 'roaring'.Lo neutral 0,Mid/Lo up a bit at 120hz,Mid/Hi down a bit at 650hz,Hi neutral 0.The 'roar' remains but I can hear more clearly what Joe's playing,Dales bass plucking is SO clear and textured,there is much,MUCH,more going on with the drum set (Jim Fox) than I've been able to discern in the past from this recording.I saw them live back in the day,and also Joe and Barnstorm, and remain a fan.Another CD that cleans up nicely is Mad Dogs and Englishmen which is quite a mess in the mids.What I have found so far is when I can bring into balance the area where the instruments and vocals are compressed together the frequencies on either side almost always smooth out with little or no help. |
@mirolab , the process you described is AMAZING in its intricacies and elaborateness. I would LOVE to spend a day watching mixing and mastering in a real studio!🎶 |
Room correction has NOTHING TO DO with tone adjustment to personal preferences. Nothing. Please read the thread for more info on this. These recent posts are more about the merits of pro balanced analog gear for tonal adjustments. For room correction go back many pages and read @mijostyn et al posts. |
As for stringing chains of processors together, if you read or watch anything about mixers TODAY, you can bet they are chaining digital plugins, and the noise & distortion simply does not add up like with analog gear. Also... those long chains are typically on individual instruments or group buses to achieve a particular effect. It would be rare to put more than about 3-4 things on the final stereo bus. Although... have you heard modern mixes?? They mostly suuuuck, and the overuse of processing is a culprit. Whether analog or digital, they will (and I will) put several processors on the final stereo bus. Take for example a typical rock mix.... I might have 50-70 tracks to work with. (not all playing at once though) But 6-10 tracks of drum mics go to the drum bus. Bass Mic & DI go to a bass bus. Maybe 4-8 or more electric guitar parts to Egtr bus. Acoustic guitars to ACG bus. Synths to Synth Bus (could be from 2 to 20 tracks). Lead vocal is likely doubled or with harmonies to LVOX bus. Background vocals to a BGV bus.... Oh yeah... let's not forget an FX return bus for all the delays and reverbs! So I've counted 8 stereo buses in this example.... and each bus has its own processing on it.... typically at least an EQ and a compressor. All these busses then sum into the 2-BUS, which might have, for example, a Tape Emulator, a bus compressor or a mulitband compressor, an EQ, and then a final limiter/enhancer. The order of all these FX also matters.... it matters a LOT! As does the gain-staging... how hard you hit each of these processors. Also don't forget that each individual track can and most likely does have some processing on it. Usually at least an EQ.... sometimes 5 or 6 things. This is why mixing is so much fun! |
@tlcocks Thanks for checking on that PEQ-1.... Yeah I had a noise problem pop up on mine. There's an op-amp chip responsible for each EQ band and I swapped them around until I found the offending ones. I moved the noisy one from the 2k band to the Sub band and the noise wasn't noticeable down there. I got Mike to send me several new op-amps and I replaced them myself, rather than send the unit back. I also rewired the outputs, as my unit was inverting phase.... a terrible thing in a studio when you are trying to do parallel processing! Mike trusted me by then, and told me what I needed to do. |
@ellajeanelle , if I may comment. I know you’re talking to @jtcf. Putting your ear up to the tweeter and hearing hiss that’s low enough shouldn’t be a deal breaker. If you have quality hi fi gear with low noise floor a slight uptick in hiss from an equalizer may be acceptable. Particularly if the music sounds BETTER with the EQ and the hiss is NOT HEARD when listening to, for example, quiet passage in classical work of well recorded piano solo. Yes, with my CO I hear low level hiss vs bypass when ear is literally on tweeter. But so what? When I play classical or piano record fairly loud (like 50% on my Bryston amp) I DON’T hear hiss from listening position. Can toggle EQ in and out and no obvious change in noise. Low is low. It’s worth the gain in tonality, harmonics and timbre you get from EQing. Look, I had a dead silent phono pre that I got rid of for a noisier Graham Slee Ascension phono pre that sounds way way better. It’s the same thing. In the end, only you can decide how much hiss is acceptable. I play Yiruma great piano recordings for people and they are amazed at what I can do to improve the way that instrument sounds through my system with high end analog balanced EQ. Remember balanced when the music is playing helps tremendously with noise floor also. If I put my ear at the speaker while playing music will I hear any added hiss? Really doubtful I’ll hear or notice. But I might get tinnitus or an earache! |
jtcf Thanks for the reply. I looked at it. I am not sure though. I looked at the specs and S/N ratio of 100db is not that great. If you put your ear right next to your tweeters (as in like practically touching them) with your ear, do you hear ANY hiss whatsoever? Please be honest! I ask because I am doubtful that the eq would be silent in that manner. Currently I hear absolutely no hiss whatsoever when my eq's are out of the loop if I touch my ear on the tweeters, but all the components have higher S/N ratios of minimum 127db or above. 27 decibels is a lot and perhaps the difference between hiss or no hiss. I am going to buy several once I find the right one and want to be 100% sure to avoid the hassle of returns. |
@mirolab , can you or anyone else enlighten me on how sound engineers can run several pieces of gear in series in their chain, sometimes like 8, and not have to worry about degradation of signal. This is as opposed to we audiophiles worrying about only one extra box in the chain. If I chained 3 pro EQs together and did mids on one, air band another, etc. would I have viable result? Or do the pros use special consoles for daisychaining that prevents degradation? It’s common practice to use a few EQs in the production process! |
Actually never mind, @mirolab. The dealer at Guitar Center called and gave me my requested test results. I asked for a number of things to be done. There is disproportionate hiss in right channel. It’s audible with quieter passages of music. That’s not acceptable to me. I asked them to service it and get back with me. We’ll see. But not now. Sticking with the Michelangelo buildout. And my 2 wonderful Charter Oaks. |
I have called about the used Charter Oak PEQ-1. It’s the right serial number. Deming era. I own 2 already. I am likely going to scoop it up, as it’s the best sounding studio stereo program EQ I’ve ever heard. That is, unless @mirolab wants it. Miro…? |
@ellajeanelle I'll leave a link for you.I bought it as a step up from the Lokius,which was my first tentative step towards parametric equalizers. I was skeptical about adding another cable and component but curious enough to try it for a modest outlay.The API is a "no frills" unit which is all I need for a home stereo.You folks that do recording will be looking at equalizers with more features I imagine.What surprised me and why I love it is how simple it is to clean up not so good recordings - uncongest them.I've only had it for three weeks so I'm pretty much gobsmacked right now.https://reverb.com/item/42746954-api-select-sr24-dual-channel-4-band-equalizer-api-562-eq-inspired?bk=eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiIwOTljYjJhNS1lODA1LTRiYWYtOGM2NC0wOWRhN2RjNzFjYTQiLCJpYXQiOjE3MDgwOTQ0MTcsInVzZXJfaWQiOiIiLCJzZXNzaW9uX2lkIjoiYzU0YWMwODctMDY4Ny00YjViLTliNzgtNDJhMWI5MTZhMWY2IiwiY29va2llX2lkIjoiYmYyMzM3YjQtMjc3Ni00ZWJmLThkYjktZGU5OWVhMTliOWQwIiwicHJvZHVjdF9pZCI6IjQyNzQ2OTU0Iiwic291cmNlIjoiTk9ORSJ9.Fh3bZbkJYtNrjKlrA_4NiZiIHGfMK2uwRtUQ2ImAbJs |
jtcfWhat is the model # of the API unit you mentioned? |
@audiorusty running the cables around the perimeter is tricky because of two doorways to navigate either under or over. Old weird farmhouse. If I decide I really want it nearby then I'll put some more thought into it. @ellajeanelle the API unit I recently purchased is completely silent in my system whether engaged or in bypass mode.I'm a novice at equalization being that this is my first professional eq component but Gearspace does have a wealth of knowledge to glean.Right now I'm much too biased in favor of what this thing does for my system to encourage anyone why or what to try.I'm enamored. |
The Michelangelo thread a Gearspace is amazing. Lot of great discussion also on digital vs analog. Another great quote: ”Agree with that 100%. Indeed nowadays some plugins "emulations" (aiming for analog color) are sounding quite great (and some free plugins are quite amazing tbh) but in a "real world mixing or mastering job" most of the times Plugins are still sounding "too much", or "too muddy", or "too bright" etc etc, where Hardware is still much more forgiving and musical. Too many time I end up bypassing plugins, where analog always stays on ” |
