Believe me I dont like it when an amp fails any more than you!!!!! I dont want to make excuses either, I am a competitor long before I was a rep for Stetsom, this isnt the first type of equipment I've used either, I just wanted those of you that are hatin on Stetsom to know that we are on top of this problem and are working to fix it. I personally have sold almost 50 of these amps here in north america and use them myself so I know what I am talking about. The question about the oga wire inputs, I use 3/0ga to my amps that might have something to do with mine holding up.....No they arent Prototypes, they are sold all over the planet and have been for almost a year. I think personally that the shipping is part of the problem too. They are getting beat up between here and Brazil. I have seen amps just destroyed in shipping especially UPS we are using Fed Ex international. DSMW I didnt come in here to set up any arguement just state our position and quell any misconseptions........
