Vintage tube suggestions

It is late 50s to 60s NOS Tele is what I am talking about. Mullard is also great as well. Mullard is little bit richer in the mid then telefunken. In my system, Tele has a better and bigger soundstage then mullard but less creamy.  Only new production 12ax7 I like is Generex gold lion brand.

Telefunken has a great 3D soundstage. I have tried lots of others but keep coming back to Tele. I use them in my pre amp, power amp and phono amp. Ymmv.

Gennerlex is good tube but they have a smaller and flater soundstage. Also little drier mid and leaner bass compare to Tele or mullard tubes. And new tubes just Don't or can't produce that big 3D sound vintage tubes make. Vintage tubes just have more meat on every note. I can't tell if there is any difference in sound between smooth or ribbed Platte. Is your mullard reissued ones?

I am not sure how vintage tubes will work in your pre or DAC but I never had a where vintage tubes didn't improved quality of my systems sound. I can't really turn and go back to using reissued tubes. In my tube gears...Vintage rule.. lol.
