Tube rolling preamp or power amp gain tubes, which ones (or both)?
I have a PrimaLuna DiaLogue HP power amp and its preamp mate the DiaLogue Premium. Both units came with six stock gain tubes each. Does anyone know if I would affect the resulting sound more by rolling out only the preamp gain tubes? Or is there more of an effect by rolling out only the power amp gain tubes? Are the "greatest" impacts produced by rolling out the gain tubes on both units?
