Any time budget matters you will find far more value in integrated amps than separates. This holds true at least until you get into the tens of thousands of dollars. Especially since what you could get for the Aragon plus what you would need to spend for the quality level preamp it deserves- plus the extra power cord and interconnect they deserve- puts you into the range of something like a Prima Luna or Raven integrated that will be very hard to beat.
Either of these, PL or Raven, will be way better than good. Why settle for decent when you can have excellent?
