If it must be 6DJ8, then Amperex 6DJ8/ECC88 early 60’s white label, non Bugle Boy.
Better sonics and low noise is Amperex 6922 PQ gold pins, early 1960’s, Heerlen.

Most musical and grainless Holland Amperex 6DJ8/ECC88?
Much has been written about Amperex 6DJ8 valves, however, it is frustrating and most time consuming to slog through the various forum posts. Here I am interested in a summary of evaluations with regard to getter style (D, Halo, Dimpled with single post or A-frame), labeling (Bugle Boy, Orange Globe, Treble Clef, etc) and year of manufacture. 6DJ8/ECC88 only, please, not the 7308 or other forms. Also, kindly spare us lectures about "best" and "depends on your equipment and ears." These qualifications are by now well understood. What is musical? Accurate, articulate, harmonically saturated... but mostly the sense of all the salient elements coming together to form a transparent and satisfying, grainless whole. My specific application is the output stage of a R2R DAC. Lastly, I am only interested in opinions occasioned by actual comparative experience with the Amperex 6DJ8 iterations. Should you take the time to contribute, you have my gratitude.
