Any active/passive preamps with penny & giles pot?

Hi,

I heard a DIY preamp that used penny & giles potentiometer at a friend's place, and to my ears it sounded awesome. Much much better than anything i'd heard before.

Now, i'm no good at DIY ... so i was wondering if it was possible to buy a preamp that used this potentiometer. Any of you folks know of any commercially available preamp that uses this pot?

Thanks!
