try the Phillips 6j5 mil. tube. looks like a 6sn7, but only 1Triod system is active inside.
Very balanced sounded, and absolutely quiet. no rustling and humming.
I have no experience with the 6f6, but I don't like the RCA 5y3gt.
I find these a bit flatter and slightly metallic, try a phillips or slvania instead of this one

I am loathe to spend much money on rectifiers. It isn't clear to me how different diodes feeding a capacitor can have all that much impact on the sound especially since the entire idea of the power supply is to provide DC to the circuit. DC, whether brought about via fancy tube rectifiers or solid state diodes, should always be the same. If different rectifiers do change the sound then that would imply that the power supply has some AC, noise, or something else that isn't DC going into the circuit.
If I were going to test that belief, the 5y3 would be a good one to do it with. They aren't all that expensive compared to 5ar4 or 5u4. Maybe the next time I put in a tube order I'll try one.
