Im looking to put a power/pre rig in my home. Young guy, miniumum wage job looking for a bigger rig. Only getting 260 watts out of my workingmans 4004. Im either planning on trading in my WM cabinet and buying a 4ohm Avatar 4x10 to get the extra 140 watts out of my amp and giving me a better tone. or Selling all of it and buying an Avatar 4x10, A cheap Power amp(behringer) and running it all the the sansamp DI. Which would be a better setup?
