    Luxman r-115 volume troubles

    Tube Pre-Amp or Tube Amplifier

    I'm a little hazy on this and the answer is probably self-evident. Question one: Which is more important to sound: A tube Pre Amp? or a Tube Amplifier? Question two: If the Amplifier is more important, can a SS pre amp feed into a tubed amp and will the results be similar or better? Or will...
