I would listen direct for at least the first 6 months. That way, you'll know what you have after full break-in. Combining the Wadia with tubes may be a good move which may circumvent the preamp. Pay attention to the power cord and cabling.
Depending upon any perceived shortcomings, you might decide upon Joule or Dartzeel or others. Steve might have some suggestions when it is time. A CAT preamp may still be worth an audition - perhaps synergy may be enough to make you want to get out of your chair.
