I have heard that Telefunken tubes are clean and quite but quite "dead" sounding!
Phillips/Siemens/Mullard/Brimar/Valvo/certain Teslas might be better options. In general for the small tubes, I have heard that the W. Europeans are the best choice and for rectifiers, the vintage Americans are the best. This I get from a pal with 25 years experience in tube rolling and he is based in Eastern europe.
