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?
Just get what you want and it looks like the Denon is your choice.

Yes, but...I really like my Parasound pair, too!  I'm like a guy who's had a good, faithful but average looking girlfriend for three years...and then I see this sexy beauty walking down the street (Cue Manfred Mann's "Doo Wah Diddy Diddy").

Best option for cheap sound- Decware. Parasound will no longer be in the
"Yes, but...I really like my Parasound pair, too!"

Can't fault you there, nice rig.

Pass Labs Aelph Zero Class A monoblocks work well with Klipsch. I have 1974 Heresy and LaScala
You mentioned an open box unit from Crutchfield.  IIRC, they will let you return within a reasonable length of time if you don't like it with your speakers.
