Emotiva xpa1 gen 2 with clsiizs

Right now I love my jolida jd3000a tube mono blocks 200wtt/ch with my tube pre amp music envoy ,but I'm soon to be in a larger room and my clsiiz will love it but will I need more power to run them at louder volumes ? So I have been looking at the emotiva mom blocks xpa 1 gen2 (600wtt/ch , class A-and A/b switchable,there new reference series. . Help I'm just a 2 channel audiophile guy and my tube sound so good and make My clsiiz sound so sweet at low to mod levels ( cuz my room is so small 10x10 ,but in a room that will be 20x30 and room for the speakers to breathe I just might need more power , so if anyone out there has these emotiva amps please let me know how they sound and any review good or bad will help ,thx fattner
