Slagle
Recently had a Dave Slagle Autoformer passive in my system and very impressed having heard various incarnations - transformer-LDR-switched att' etc etc....
That's where my cash would go but I have two passives wired 47 Labs and Western Electric with a specific Bourns pot that just work so well in my kit.
I keep them hanging around as back up to the iFi Pro pre' as Bourns though not a flash audiophile name supply to the medical, industrial and the automotive industry since the 40's with an unbelivable catalog of precision potentiometers.
