The UPA-2 would be a good choice and as new you'd have a warranty. Used I'd look for Adcom or Parasound. In my opinion the Adcom is a more robust sound than NAD. The only Parasound I've owned was a 750, it seemed to be more clean sounding but lacked the bottom end of Adcom. You wouldn't need much power for the Klipsch and could pick up an Adcom gfa-535 for under $200.00, or maybe a newer gfa-5300. I'm not sure how much Rotel amps go for on the used market but that's also something to look at.

If you can hold out Emo usually has a party or open house type of thing during one weekend in the summer and they give good discounts to visitors so your money could go further at that time. I think it's called "Emo Fest". Keep watch on the site or listen to their Podcasts.
