Been listening to 596/SP 274B + Raytheon 6EW7 combination on my HD800 and would personally say I like this combination on the HD800 with the expansive soundstage and softer bass though it lacks the attack from the 6FD7 and doesn't sound as tubey compared to stock RCA 6EW7.
596 is pretty bass light, i do not like it combined with 6ew7. though sophia/6ew7 is pretty good all around.
