The Raytheon sounds the best in one of my systems.
It doesn't sound like the others, it has it's own character.
But of course a lot depends on preferences and synergy.

The NU is the 1st 6F8G I have tried so I am unable to compare it to others. I find the NU to be well balance tonally with outstanding midrange. I am a bit surprised at the difference the rectifiers make in the ECBA. I can hear a bigger difference in the 6X4 than in many of the 6SN7's I have rolled.

Do you mean amongst different makes of 6X4, or by substituting different types of rectifiers?
Amongst various 6X4's

Some people find some enjoyment in the visual appearance of the tubes. It doesn't have to be only about the sound.
I'm a little tempted to ask what the point of your post was, or why you felt it necessary to be so candid with it, but this is the 6SN7 thread so I'm simply going to leave it at that.
Well,EX,you were right..this tube gives off a really nice visual appearance..I stand corrected on my earlier remark.
Just got delivery,an hour or so ?
Going through some of music files now,and also have the Phillips 7316 mini watts in the 12au7 input..
Right now,I am hearing a nice increase in SQ ,over the TS-5998..but ,not a night & day difference.
