I use it for two years in all possible configs: bridgeable to mono audio with a subwoofer HK in HK sattellites sétéro two and also home studio tannoy pbm 6.5 with what i I love the most, it musicality and the start of the fan  if the amp,overheated  very nice home studio, what I like least, it is buit  3Units 
I tried other models before: crown us carver audio and low-end
I would definitely do it again this choice
