Simon- There are many who believe that a good tube pre-amp is a better upgrade than almost any SS pre. Of course, there are those that differ. If you have no other source but the 4000 and if it has a variable output control, then keep the IC cables short and run the output straight into the amplifier section of your integrated. You may find that it sounds better bypassing the pre-amp section of the integrated. Good luck.
