Better Amp for Cornwall IV's...

...Parasound 2250 v.2 / 200 Pre combo, which I own, or Denon PMA-1600NE integrated, which I don't, but I admire the build quality and appearance of?  My Parasound is rated 275W into 8 Ohms / 400W into 4, while the Denon is 70W into 8 and 140 into 4.  Of course, the Klipsch Cornwall IV's are quite sensitive and are rated 8 Ohms.  Maybe more than which is better, which would you all prefer?
