HELP!!!! Newbie looking for a decent 2 channel power amp in the $1,000 range

I am trying find a decent 2 channel power amp to replace my Sonos Amp connected to Kef R3's and RSL Speedwoofer MKII.

I was considering the Emotiva TA2 but based on the comments/reviews here I beleive I could do better going 2X on price over the Emo and be open to a used unit.  I prefer  warm to neutral with detail sound profile.I'd also like an amp that is north of 100 WPC becuase my listening space is midsized (open floor plan approx 600 SF).

Thanks to all in advance!
