Shorting the speaker wires

The X-terminators are locking bananas but, apparently, they were not tight enough.

When you reterminate keep one wire an inch longer on one end and an inch shorter on the other end. That way if they do pull out they don't touch.

Brilliant!

I feel sort of like an idiot in saying this but when did crossing my speaker wire terminations become a stereo system catastrophy. I blew the S*** out of an SS amp by doing just that a fews years back. Now I am hyper to the extent I can muster hyerpertude.
I still have this thinking from my first days as an audiophile that you can safely touch a "live speaker wire" and must have crossed them a few hundred times in the 1970s. To this day Ralph Karsten will drop a quarter on his binding posts -that stops the sound- but once removed causes no apparent damage. So my question is literally. When did I need to be worried about this?
I bought a McIntosh 2505 that had a difference in gain between the two channels at a discoount even by used standards. I then had one chanel go altogether for no obvious reason, but I am very certain it was not idiotic crossing of speaker wires. My friend's Dad fixes all things (has an EE and experience) and managed to get this piece back into it's original state of partial disrepair. My friend told me that I shorted the S*** out of it. I denied it. He couldn't help himself and insisted I did so repeatedly because his father whom I really do admire said I did.
I knew I messed up the other times this happened this has happened all of twice, in the last 7 years. It's not exactly bland. There is no mistaking the flames if you get my gist. I simply did not this time and haven't had other problems. I never had a directly voltage coupled output from the speaker posts to my knowledge. If crossing wires were as bad as they have apparently become or were, I should be quite dead by this method which as of this writing appears to be a very innefective technique.
Obviously I take nothing for granted anymore.

Yeah,I've done that on my Mark Levinson 27.5 amp,years ago.
I was using the Monster bananas and speaker cables.The bananas accidentally touched because the speaker cable was so heavy gauge that caused them to slip.Nothing happened to the amp ,there is a protection circuitry that kicked in and saved the amp,but since then I covered the bananas with shrink tube socks.
Hope your amp is fine.
