Trip,
I'm using JTL-5670 Tungsol black plates D getter 1959, straight after i plugged it in, the soundstage became so wide and deep, at first i thought something was wrong with my amp, normally it gets pretty loud around 9:00, then i realised the soundstage has expanded so big the sound became relatively small, so now around 10:00, i get an amazing dimensional sound.
Tungsol is more versatile than stock tube, in a sense that it's smooth the same time very dynamic, not only does it sound good on classical, it excels in jazz and rock as well, the drum solo from the album "time out by Dave Brubeck" sounded so real, i could picture an exact size drum kit in front of me. On classical Tungsol is smooth but it doesn't have the sustaining effect for instance the violin sound, on this particular point i prefer the string instrument sound from stock tube. I highly recommend tungsol tube.
