I am looking for an old style THT digital log-pot that has an amazing sound, but I am not able to find any advice on the subject.
There is among other the MCP4162 but is it just a log-pot or is it in fact a hi-fi log-pot.
What do I have to look for?

It is a potentiometer that is meant for sound and is adjusting the resistance values logarithmic instead of linear.
Many pots are made to adjust electricity and noise, distortion and so on is utterly without any concern. 🙂

You are comparing a mechanical entity ie pot to active electronics.
So it comes down to what’s your criteria as far as, what’s it to be used for? specs, control etc?
Look at a TI pga2311 part, would it suit your application? The log aspect is just the gain or attenuation vs a control setting

The idea is to make a volume control for a simple preamplifier, I imagine to having phono in -> 47k impedance resister -> volume control -> output buffer -> phono out.
The chip looks very interesting, the question is if a nonvolatile chip is of advantage?

Phono amplifiers are usually fixed gain devices followed by a preamp that has variable gain
volatility as in, volume level settings at power up is a system design feature

Look around this forum, many examples of pre-amplifier designs using active electronics but remember most electronics means require some sort of control usually done by a Mcu
Yes thee is a lot of solutions with coding and complicated techniques, I could not find any with maybe a simple pot-chip with any talk about sound quality.
Muses 72323. A member here sells pcbs. A stepped attenuator can be a more satisfying choice though.
If your sources are digital a modern DAC can be used with internal digital volume control which has matured in a way. Two birds with 1 stone.

Take a look at this
PGA2310
I bought this board a few years ago and it works flawlessly, and good sounding.
I would take the complete kit with display and remote control unit that remains cheap enough.
My choice was for Single Power type for simplicity of internal wiring, however I am not currently using it.
Unless you want to insert it in a device you will need a case.
Good find. PGA2310 ain't bad either but one rarely sees it with a rotary encoder mimicking a traditional potentiometer. Rotary still is the ergonomically best way to control volume for many. The one that invented + and -button volume control should be sentenced.
The dual supply type with remote control PRO2 seems the better choice and as one will need a PSU anyway why not a +/- 10...15V type?
BTW beautifully built amplifier, not DIY I think?

I had bought this too (always with PGA2310 inside) built so very well
Burson Audio Conductor V2
The remote control had the same code as my TVC Panasonic, so if I was simultaneously looking at a tennis game by listening to music also I could not adjust the volume of music because it also changed the TV channel.
Contacted the Audio Burson they advised me to cover the IR receiver on the preamp. 🙄
Returned, but it sounded so good.
P. S.: You're correct. I chose the dual power board (slightly more expensive), but I didn't remember that right now.

The Muses are slightly better than PGA2310. Unfortunately many designs lack buffers which these volume control ICs often need for optimal performance.
Unfortunately, you do not seem very clear on what you want.
Logarithmic, or linear just describes the resistance curve of a potentiometer. Log. matches hearing, so that is normal.
Do you want a digital sound control where everything is done with the digital signal?
Or do you really mean a remote control for volume? They can be different things.
Do you want to be using a potentiometer / variable resistor? Or a stepped attenuator which can be a rotary switch or relay-controlled switching.
Audio quality will then depend on the quality of switches and resistors. From a few £-$ to many hundreds.
If I mean? 😵
Frankly I don't know what you are talking about! 🥷
Indeed, I don't remember... 😀
