Will you take $700 now and the balance on Thursday? Just need to move some money from another account. I've been here over 10 years, here is my old feedback:
It is not a big difference, more refining of the Graham Slee sound. Giving it a more tube-like sound with smooth, velvety midrange and subsumed treble and awesome bass. Yes, you can obtain more control of your sound using a tube amp like the Crack, Pan Am, or Lyr. But, if you want the best of both worlds, I highly recommended.
