Yeah sorry that was my mistake with the first impression post. What I meant was that 6922EH has wide sound stage, but in its stereo image the vocals are not as balanced as I would like. Thats why I said that the vocals should be further. Rocket, even though sounds narrower, has balanced separation with each instrument. The band I'm listening stays intimatedly in front of me and the vocals stay nicely in the middle of the mix. I think with small tweaks the 6922EH could be awesome. Just need the vocals to sit better in the mix. If you understand what I mean and know a tube to fit my needs that would be much obliged.
I think its easier to draw what I was talking about. In the first picture, rocket on the left hand side and 6922EH on the right hand side (x = listener, v = vocals). In the second picture the upper "v" describes where I feel the vocals should be (Kind of three leaf clover 6922EH, where vocals were a bit further, would be awesome):
Edit: I agree 6922EH is far superior tube for electronic and ambient music. My 6922EH doesn't need any more volume than the rocket. And sorry for my drawing skills
