maggie SMG sounds dead

Listen to the speakers with and without the fuses. If there is no difference the tweeterwire has broken.
Also rodman and hifitime have good suggestions.

I had a similar experience when I first got back into audio after 15 years or so. It turned out it was mostly me (my ears), partly my system needing to "break back in" after not being used for so many years and the addition of a power conditioner help a lot. After some research I found out that the power here in the Hudson Valley is pretty bad. My system used to sound it's best in the late hours of the day and sometimes unlistenable during the daytime hours prior to the power conditioner. Try just listening for a while and see what happens.

Yes,its been known that electronic's setting around unused may have electronic parts beside mechanical parts that will settle into different values and change sonically.Dirty power is getting fairly common.Mine is a nightmare.Talk about ears changing,what about those people that have cars stereos you could hear blocks away.They might be wearing hearing aids by the time they reach their 30's.

just got back from a trip and read all posts, everyone is very kind and thank you. Will do all as suggested, i have a sneaking suspicion that the comment about ears and sound appreciation having changed is near the core of it. off to barcelona for a few days then will try.

Finally got a few spare minutes, so removed fuses and absolutely no difference, stripped off one cover and everything seems in mint condition, so breaks obvious.Seems odd that both HF panels are dead. I dont suppose the capacitors would blow ??? Is it a lost cause ??
