Parasound A21+ or Emotiva XPA-DR2


Choice amplifier for a modest two channel setup.
Do you go for 160w/ch A21 with greater detail sound?
Do you go for 550w/ch DR2 for the punch and impactful sound?
Speakers in play are Paradigm Tributes. Speakers and room work either way.
Which way would you go and why?

(I've looked long and hard and can't find a hint of an actual review on the Emotiva DRs at all. They've been out for a while now.)

Thanks for helping out!

I'm still not sure what your point is.  Different technologies... have you listened to either amp or do you just look at pictures on the internet.  I would suggest that there are a lot of reviews available on both amps including numerous owner reviews of the A23 -  http://www.audioreview.com/product/amplification/amplifiers/parasound/halo-a-23.html
I heard a Gold Note P-1175 (?) vs the A21 and thought the Gold Note had more detail and a LOT more foot tapping (musicality) than the A21 
Thanks for the help!

In the end, I went with the Parasound product and am very happy with it, at least until the urge comes along to replace it with something else as is the usual course of things.

I did find one review on the Emotiva XPA-DR2 from hi-fi news. Anybody that's interested, click the link below.

Parasound Halo line punches way above it’s price point. Many of the Halo Line has been designed by John Curl and I often think it is better to look not at a product brand or model but ask “who is designing and engineering” the piece I might want to own.
