Unsure on how to use the presets for that ?

WiiM Ultra Streamer Preamp Review

Btw it takes time anyhow , i use the auto sense for optical for my CD and it's not fast even auto switning to optical
Input is one of the settings you can assign, you might not need the other settings, so you can turn them into effectively dumb input selectors.

There are actually 8 presets on the remote.
Double-tapping preset 1 gives you preset 5 and so on.
It works with presets, a bit easier.
It also works with auto sensing on both line in ( from my phono stage ) and optical ( my CD player ) .
But still slow .

Pre gain ? Is it aplied before all processing like EQ ? Can it be used to avoid clipping with positive EQ instead of the volume limiter .
It’s a neat feature I didn’t have in my previous WiiM ?

For reference the latency test shows 31 ms for me with a pair of digital KEF LS60 as the speakers assume this is to my listening position and includes processing in both WiiM and speaker ( there is EQ in WiiM , sub xover and phase comp in Kef )

Yes, this is how pre-gain is expected to work. Since pre-gain can be either positive or negative, it could also cause digital clipping if applied wrongly.
Do you really have different EQ settings for different inputs? If not, setting a volume limit (0.6 dB per percentage point) is more efficient in avoiding digital clipping due to positive EQ values.
NB: Pre-gain should be now be available on all WiiM devices.

What is isp? Inter sample something?

There is no single fixed headroom sufficient to cover all kinds of inter sample peaks ... and inter sample peaks always mean faulty productions.

No...
This type of clipping "during conversion" is omnipresent (except in classical music).
The sound engineers admit they aren't concerned about it, and the practice is omnipresent in warfare at the level of... it's accepted. ("but doesn't seem to bother them"..)
but they pose no problem if the precaution is imposed on them
Need just true peak meter..
But somes dac like rme msb etc etc use -2or -3db in input for that..
What's striking is that this rarely crosses over... and this is quite easily explained in classical music.
but renders obsolete, even idiotic, the race for bit perfection "in the name of quality" which motivates so many people...

I currently experiment with different EQ for my turntable 
I added an extra “rumble filter” the phono stage already has a subsonic filter ( but probably insufficient) and I assume my closed box subwoofers has thier own protection ditto my active speakers . So maybe not necessary, but hey it’s my new toy must try stuff …

A look at the music library: How much DAC intersample overhead is enough? True Peak analysis of genres in an eclectic digital collection.
A blog for audiophiles about more objective topics. Measurements of audio gear. Reasonable, realistic, no snakeoil assessment of sound, and equipment.

See also plenty of interviews etc. with sound engineers acknowledging that the practice is common...unless the client objects or certain types of music are demanding "where it would be too noticeable". ;-)
So the requirements for bit-perfect, high resolution, etc., inevitably raise a few eyebrows.
But it's not hard to get around... you just have to be careful.
(See services like Spotify, which encourage users to respect a -1dbTP limit, TruePeak, which requires content providers to adhere to it, etc.) etc. etc.

Archimago clearly showed that 3 db is not universally sufficient to fight ISP.
He also clearly states that ISP is the result of faulty production.
Period. Yes.

It might be wise to increase the margins even more, indeed...-5db etc
I don't understand your point (perhaps due to language barriers)...
whether it's a bad practice or not... the fact is that it permeates a large part of production... and is widely recognized...
It's the fact that it doesn't seem to bother anyone that's the question...
brutal digital clipping..but generally brief
Their frequencies are simply considerable...
Sound engineers readily admit it...

I didn't say that Inter Sample Peaks don't exist. My point is that if you care about this (because the DAC designer did not), then a margin of -3 dB is no guarantee. Obviously we didn't understand each other too well.
I'm impressed by the auto switching of inputs, it's never failed to switch, it's never switched when it shouldn't, and I think it's a reasonable time in order to get the first to 2 points right. My MC phono stage isn't noisy enough to switch when not playing music, which helps, the stylus hitting the groove is loud enough to trigger it, I never need to manualy change inputs, with how I use it.
