Upgrading to Nagra Classic Integrated Amp or Nagra Classic DAC First?

Hi everyone,

I recently heard Devore Gibbon X with Wavac pre/amp and Nagra Classic DAC.  The system spooked me because it sounded so “real”!  I absolutely loved it!

A week later, I took the Devore home.  After the speakers were set-up with Pass Int-30A and Aqua La Scala Optologic (with Millard 6201), I found the realism and sound stage lacking.  My Pass and Aqua already performed handsomely but the Nagra and WAVAC is a comcompletely different level.

Since I really want the Nagra Classic DAC, I have decided to upgrade to Nagra Classic Int as well.  I can only do one upgrade at a time.  Should I upgrade to the Nagra Classic DAC first or the Nagra Classic Int?  

Thanks!
