pros that I see for each of them. Edifier C6XD optical input dedicated amp extra connections $6600 NT http://www.edifier-international.com/products/edifier-multimedia/c6xd Edifier DA5000-Pro Bigger sub (8" vs 6.5")(freq response 20Hz vs 50hz) more powerful (108 vs. 80 watts) $7500 NT http://www.edifier-international.com/products/edifier-multimedia/da5000-pro Will an optical output make C6XD sound better than the DA5000-Pro? I really like them both. Please hlp!!
