What is your favorite tube for a preamplifier ?


Personally I like what the classic 6SN7 vacuum tube does
for opening up the soundstage and the 3 dimentional images it produces,along with the 5AR4 rectifier tube.
Please add your opinions and why.

6SN7s are nice as they have a low microphonic aspect. They are great in line stages and can handle a lot of current so wide bandwidth is easy. Although they have less gain than 6DJ8/6922s or 6H30s, the reduced microphonics compared to those tubes is profound- so it is easier to make a line section that is neutral with the 6SN7. Of course you can hand-pick the miniature tubes for low microphonics, but in doing the same for the 6SN7s the same advantage of the 6SN7 is realized.
