Parasound Halo JC-1 -VS- Bryston 7B-ST?

Ruka, I think you are partially right. There are many run of the mill amps out there that don't get damaged from crossed terminals. They just shut down. Turn 'em on, they work fine. High power amps have more current movin' thru, so more potential for damage. That said, if an amp is properly designed it should be protected against self destruction. A good designer should know how to design the protection circuits to prevent this. I knew several tech guys who played around with amp modding and designs. One of their pet peeves was high style designers who thought they knew it all but these guys would show me the weaknesses in their designs. Couple years ago I borrowed some JC amps from an audio friend. I thought the toggle switches were cheesy as were the binding posts. They sounded good, but they had some veiling and grain. Yeah,I know all the talk about thousands of hours of burn in, but this guy had them on playing music like 24-7, so they had lots of hours already. After borrowing them, i didn't think they lived up to the hype. One day he called me to tell me one blew up. I looked at it, and there was burned up stuff on the boards. He said it just happened while they were on playin' tunes. I had wished my techie friends were around to take a peak, but they all moved and I moved....
