Dear All! I am quite new here... Planning on building my first 2.0 system (music+movies) on a pair Klipsch RF 82 ii-s. I was thinking about getting the Emotiva UPA-200 as pwr amp for starters (with Emotiva XDA-2 as DAC+preamp). Any thoughts on that? Is there a significant advantage of the XPA-200 over the UPA-200 in terms of these speakers? My other choice could be the Marantz PM6004/7004.
