I just got a pair of Urei LA 4 in my home studio when I patch it to my Mackie board... the sound that coming out is very bright and clean (lack of bottom also) I'm not sure that this kind of sound is the character of the LA 4 or not. Coz' when I listen to my old Urei 1178 I can tell unit have character not like LA 4. Do I miss anything like... little modification at the out put strip or.
