Tone controls -- assuming you're ok with them, when would you try them?

So, I'm learning and experimenting w/ speaker/sub placement. I've had some success. Presently using my old Adcom GTP-400 preamp (treble, bass, and loudness/contour controls). It's likely my next amps won't have tone controls (nor balance). 

Beyond compensating for old/bad recordings, I realize there is, nevertheless, a standing debate whether tone controls are worth the (likely) sound degradation. Imagine that debate was settled and tone controls were deemed worthwhile, overall. IF you'll stipulate to all that, my question is this:

QUESTION: If the sound is not right in your room, and you've placed speakers as best you can, what do you try next? At what point do you go for tone controls?

Perhaps some just go for tone controls from the get-go…happy to hear from you all, too.

FWIW, I saw this nice list from @erik_squires on this topic:

Tone controls help us compensate for differences in recording trends across decades of recordings.
Tone controls help us adjust our sound quality to different listening situations and volumes.
Tone controls help us adjust for speaker placement.
Tone controls are much cheaper and more efficient way of doing this than most other solutions.
A good tone control is a lot easier to implement than a good equalizer. Fewer bands so more affordable to use high quality parts.

I personally use tone controls to boost the bass at lower volumes and boost the treble a bit.

Reasons:

1) For the treble, because of our age, we lose hearing at higher frequencies.  Anyone who denies this must come from another planet.  So, it compensates for my loss of hearing at higher frequencies.

2) For the bass, the human ear does NOT have a flat response like the output from an amplifier.  Far from it.  At low volumes, bass is not as hearable as it would be at higher volumes.  It is just the way our physiology is.  In the 70s that is why the "loudness" option was on the devices.  I wish they would bring that button back.

So, my advice to the audiophiles who convince themselves adamantly that their hearing response is a perfect horizontal straight line, I suggest making an appointment with a hearing specialist to bring you down to the real world.

Insertion of EQ between pre and amp allows use for all sources.

In an all digital system, where the DAC is used as the hub for more than one source  the EQ can be inserted between DAC and pre.

The Loki is a quality piece, at a price that allows one to explore the use of EQ without distracting much from funds that might be allocated elsewhere. Does require the cost of another pair of interconnects however.

@mesch Thanks! Yes, interconnects...oy.

I find the anti-tone control fanatics to be the modern day equivalent of corset wearers. Rigid adherence to an aesthetic without much practical benefit
. LOL, I agree Eric.
