They dont not even close , the D Sonic is like Wyred 4 Sound pretty much the same . the D Sonic runs 3100 and the Wyred is 3600 so its really not fair to compare to the Emo amp . I owned a Theta amp and sold it when I shipped my Kef Model Fours to Alaska , I then tried a few Emo amps but really didnt care for them . Anyway enjoy your new amp you got a nice system , wanna buy a 4520ci now ? lol
