I have been in the market for a new amp for the past few weeks and each day that I browse, I constantly see a new Genz Benz Shuttle or Streamliner for sale. Are people buying this amps based on word of mouth, playing them for a few weeks, and selling them off shortly after? Does the overall weight become a deciding factor in the overall purchase of these amps? (the shuttle in particular) Don't get me wrong, these things sound GREAT, but I was just wondering why? I was going to take a shot at one of these, but I also just wanted to know the current opinion on them as far as resale and what not is concerned.. Can anyone provide a little insight on this?
