Some like the Alps pots (my AVI had a motorised one) but others don't so I don't bloody know...
My Crown D-60's had what are now pretty Sh#t carbon 25k log pots, made worse with small diameter shafts. On the first pair, I fitted a small pair of film linear ones (Vishay?) and these did seem on headphones to be slightly better, but the law was all wrong for audio use. On this set, an anguished plea to the Crown people in the US came up with the pukka replacements which I fitted and forgot they were there. The second tatty pair of D-60's I was given a couple of years ago also needed pots. Crown US didn't want to know at all, so I found a quantity of what look to be guitar pots of the right value but with conventional shafts. I fitted these and replaced the knobs (missing trims here and there anyway) with Marshall look-alikes which aren't so different from the originals. Function restored and no sonic differences to worry about.
The only 'pots' I ever had any sonic concerns over were the cheap attenuators as used in the Tisbury. I have a couple which I used in my home made passive and I convinced myself that 'something' in the music was missing. This unit now has the 25k log pots as I used in the tatty pair of Crowns and I'm sure it sounds just fine now...

Based on my limited experience, I think the application is as important as the pot. Also maybe a matter of taste. So many people swear by Noble pots, yet the two I heard were “glassy” in comparison with the Alps Black and Blue they replaced.

Yet when a certain company does this, it's taken the piss out of.. Croft does the same, but it may be for him that more expensive pots aren't worth the extra rather than being 'worse.' The cheap pot in the NVA amps was mentioned here by me. If you recall, it was in response to you citing a £6 bass unit (trade price in the 1980s) in the SBL as a reason for it being no good. My point was to show that you can’t assume anything by quoting a price. Anyone wishing to check this can look back. The posts are still here. I still have a spare Omeg pot in my tool kit. Dorothea Mackeller biographyI certainly don’t and won’t take the piss out of the choice of pot. It’s a great sounding pot and I have said so consistently. I’ve been even built a couple of passives for mates unsig it and also said that here. Personally, I wouldn’t pay retail for any passive when I can make one for peanuts, but others can make their own choices on that, Same goes for the Audio Innovations guitar pot. Apparently they were 75p each in bulk. The NVA is £1 approx. Both work well in their respective applications. That looks very like the cheap Chinese pot in my cheap (£20) Chinese passive pre-amp, which actually sounds very decent!

And was the comparison level-matched?

Not sure and I agree it can make a difference in some cases. The hardness I heard twice was enough to me off but I remain open to hearing a Noble in another preamp and liking it. Lord knows I’ve heard Alps Blues in enough good and bad amps. Definitely not level matched with any accuracy, other than making sure they weren’t sat wonky Off topic rant: Dear Apple. Can you sort your fecking predictive text out! If I type “Noble”, you don’t need to automatically turn it into “nobleman”! Just one of many bizarre examples from the latest iPad. Is this what I “upgraded for?” Rhetorical question btw

In the uses I’ve heard it, the thing is stupidly good. £20 for a passive is right up my street too, not enough in them to justify big money for me, especially when I won’t use stepped attenuators. 24 step,in particular just never get the volume right for me.

An interesting way to,do a stepped attenuator with fine and coarse adjustment. I find conventional ones far too crude and would never have one. Andrew Rothwell seems to have thought about this instead of just sticking in an off the shelf stepped attenuator,
