You need to get rid of those large peaks caused by ticks and pops anyways before they reach the speakers.
I would not be afraid of short recovery generating the click. It is about energy. Short impulses = small energy.
In the digital domain one could do content recognition through dynamic, harmonic and rhythmic analysis and simply disallow anything that's random and out of time with the music.
I thought you were afraid of analog clicks. Digital domain audio is so slow compared to good amplifier.
BUT - do not forget digital missfunction (failure) !!!!! This may generate horrible and dangerous signals.

Okay if want analog then differentiate on the average power of the music and use that signal to suppress the clicks and pops. Drums are problem. But then keep track of the beat. A click or pop in time with the rhythm wouldn't be as noticeable.
Does your OPENAMP1 pre riaa input diodes handle this and/or the overload tail afterward ?
Using 1N4148 diodes:

Perhaps a perfectly appropriate diode could be chosen ...

No, they are there for the reason to prevent damage by ESD discharge. But the preamp was tested to input overload and vinyl clicks and pops and IMO the behavior is more than satisfactory for use with vinyl records.
I think we are talking about attack and release of gain reduction to lower the power of pops and click. Not simply clamping which can cause enormous levels of distortion.
These diodes go against rails, no clamping, not against clipping, just to protect input against bad manipulation with cables. And they work, I can make you sure.
I was thinking the same thing essentially, do I need good SR to enjoy a pop? No... doesn't matter so long as SR is music compatible when the pop is over. Same for clipping. How many amplifiers wouldn't qualify for that?
Also my current amp is low power. I don't mind that the DB'S can't go adobe maybe 100, 102 absolute limit. 110-115db transients are not something I need for the music to sound good and dynamic. It clips in such a way it's unnoticeable unless driven into oblivion.

You keep using that word. I do not think it means what you think it means.
Ok, I mean signal triggered decaying burst of granular noise, including VLF noise.
There is a range of decay times, and the subjective effects are dependent on the programme.
Reduce this system noise behaviour and any system transforms to clean, clear and musical.
This is what I have achieved/still exploring.

Not supported by real data. IME a fullscale pop has a maximum slew of a half full scale in one sample period so at 96K and even 100V rails you get ~9V/usec.
