I know these are fairly popular power amps around here, and I've been loving my 2.0 for the past 6 months. But, it sh!t the bed during a recent gig. I don't know what exactly happened....would power on, but make no sound, with the green ACL lights flashing with the input signal. It's at an authorized repair shop, so as far as I know at this point, it's being handled under warranty. So, now I'm just kinda wondering what kind of reliability other users are having with theirs. I haven't seen any issues around here, so I'm hoping it's just one of those things. I'm sure I'll be a little apprehensive using it again, and that blows.
