I have owned the xr100 for five years , driven by a McIntosh mc252 amp with a McIntosh MX-121 control center; main source for music is a mac mini with external HDD coupled to a PS audio perfectwave DAC using ROON software. My previous speakers were KEF reference 3 (old models). I do not have the possibility of listening to hi/fi gear very often. I can tell you that I not 100% satisfied with the XR100 , somehow they lack finesse and the high frequencies are bit too harsh for me .They need a lot of power ( you will have plenty of it using the mono-blocks) . I wonder if focal kanta 3, revel ultima, sonus faber olympica 3, or KEF new reference 3 could be a better choice , but have not heard any of them . Regards
