If the tweeters aren't blown now then you should be o.k. but I don't know if I would press my luck for too long. As far as the pink noise goes, if you hear it with no inputs to the amp then there is definately something wrong and would look into it regardless of if you hear it with music or not since it may be a sign of worse things ( that will blow your speakers ) to come. If you bought the amp local I would call the shop, if not then try Madrigal to see what they say. The amp might just be pissed off at your a'gon name ! Try changing it to Madrigal-man and see if it helps??? No, really good luck on finding a fix.
Pink noise and pop from Levinson 333 amp
Please help. My ML333 amp makes a pop sound on the speakers when switch to ON from Standby -- I can hear the relays clicks inside the amp then follow by the pop (sometimes it pops going to Standby from ON). Worse yet, when it's IDLE (amp ON but not playing music) I can hear the amp puts out pink noise on the upper-mid and high drivers (my guess is 2kHz and up) when my ears are 2 feet away from the speakers. The noise (hiss?) is there with or without the preamp connected. Does anyone know what are the problems? It shouldn't be the from the main power because I don't get this problem on my Denon home-theater receiver. Thanks in advance.
