Equalizer in a Hi Fi system

@mahgister , your ‘natural’ method, while impractical and unsightly to wives, is certainly fascinating. I have no doubts you are maximizing sonic returns on the gear you have. 

Yes. I mention it for information only and for those who have an audio dedicated room only for experiments..

 A single straws change S.Q. in my experiments .. 😊

My wife will divorce if i tried these set of experiments in a living room and she loved me ..

 I use with success three analog EQ. for sure  but basic one unlike yours  though very well implemented for my needs ..

"Special color sauce" pretty much tells it like it is, and whether such a flavor is a benefit is obviously system dependent, a matter of synergy or personal taste instead of being a desirable trait or character sought in every case and system context. 
 

you are missing the point a bit. The best analog EQ boxes are simply amazing sounding and extremely musical and resolute. Many a mastering engineer says just passing a signal through the box set on flat but EQ in makes everything sound better. With the right box, you can make your system sound whatever way you want tonality wise all the while enhancing the hi fi charteristics we all pay attention to: timbre, image specificity, staging, resolution, PRaT, etc. The term “color “ loses its negative connotation in such a context and the term actually becomes irrelevant. Great and right sounding is great and right sounding. Period. You don’t know until you’ve tried. I can tell you that with one of these EQs picks, fret slides, breathes, pedal clunks, all the micro and macro resolution is there in spades. And for all of you with the Loki Max thinking you know what I’m talking about, you don’t. You think you’re hearing what you should be getting, but you have no idea. LM has been in my system and fell woefully short of my PEQ-1. Returned it the next day. Piece of “Schiit” in comparison!

At this point I would repost what @dgarretson said on page 10 to further build upon what I just said:

”

I have nothing to add to this interesting discussion except for another vote for the Manley Massive Passive. I purchased the latest version with switching power supply, initially to complement a custom speaker with a Purify 6.5" mid woofer and matching passive radiators that handle LF boost well enough to produce high quality bass to 30hz. Over time I’ve used all bands of the Manley with excellent results.

After break-in and experience on how to optimize its relatively complex and sometimes counter-intuitive controls, the Manley piece has become an essential component. It is a bit fiddly to tweak, and once set up properly, wants mostly to be left alone. It has a clean, open sound with tube characteristics that don’t sound "toobie." No hiss on top.

Of course it is well vetted by mastering pros-- which encouraged me to skip past lots of cheaper solutions.

I’ll add that at this level of performance, a studio equalizer is a seductive and cost-effective opportunity to improve a system without endless component and cable swaps. Perhaps an endpoint.

“Question:

electrically speaking, can I run balanced equalizer into a tube amp and boost the signal without damaging tubes or amp?  Cannot find a definitive review of this topic anywhere online. “

I talked to two sound engineers and got my answer. The answer is yes I can without any risk to tubes or equipment.
