For five grand you might even consider Krell, although I have never heard one of their amps and don't know how much benefit they'd offer over a Rotel or Classe or even an Outlaw for that matter. Others around here may have more experience with amps in that price range.

My father-in-law's two-channel system (BAT pre, Audio Research CD player, Spendor speakers) uses a pair of bridged two-channel Classe amps.
