I got NAD T743 A/V and have Totem Arro speakers connected in my leaving room + sonny cd (will get better player soon). I am really using it for music only but bought T743 in case I would add plasma(which may never happen because I have home theatre in basement). Would C720BEE sound much better with Arros? Did I make mistake? Should I try to change to C720BEE. Any comment, help apreciated, thanks
