I did receive the PM, but I will respond in the thread so others can chime in and give different prespectives.
20 x 25 room and Polk Audio LSi's you say? At 4 ohms, the M25 is very powerful @ 255w per channel. IMO, the M25 will be beneficial, especially in the long run. With that size room, the Denon is effective but you may experience fatique over an extended play. The NAD give you consistent performance over the long haul. Are you using the LSi's internal subs fo your low-end or are you using a stand-a-lone sub? That can make a difference in performance and sound also.
