Hi and i agree about the linear taper not suitable for volume control
But a small resistance can vary the attenuation curve
I think that a very important factor is the quality of contact between the resistive layer and the wiper
The superiority of discrete attenuator i think it is due to this ... a better contact meand less noise that is then amplified downstream
I think that cermet pots are better than conductive plastic pots in this regard ... less noisy
But i have to try and listen
Kind regards,

The best faders/pots I have used are Penny&Giles which are used in most high-quality mixing consoles. They are conductive plastic jobs but also very expensive, too expensive for most HiFi applications.
Hi and i know the brand, very famous
Clearly not all the plastics are equal ... I am just curious about cermet pot
Maybe i will be disappointed
In general i like pot more than attenuator
I prefer a smooth action ...
Looking at the P&G it is more value than my preamp ... very beautiful
It is a pity to put it inside the box ... what a nice part.
Kind regards,
