This tube sounds wonderful. Great extension, nice mids. Getting preamp grade ones out of a batch is more difficult, so at this time we only have stocks that are Driver Grade; which means they're not really suitable for use in preamps. Hopefully we can find some more tubes that test Gold or Platinum, because they really are a bitchin' sounding tube...

Driver/Buffer grade - Lowest noise but not the lowest in microphony. Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.

If you have a preamp or phonostage, this tube will not be suitable for use in those circuits.
