I was working on my laptop listening to music through my setup and I heard a sharp, loud snap like a balloon pop or bang snapper.
I thought I blew something in the preamp or amp.
I check everything as best I can. All seems to be working fine. I sniff the gear. No burning odors. Both channels good.
Any idea as to what may have happened?
Setup is a Assemblage L-1 single tube preamp, B&K EX4420 amplifier, Hsu Research HB-1 speakers. Source is an old imac feeding a Dragonfly.

I hope that sound wasn't coming from inside your head.
Seriously. Stroke victims have reported hearing stuff like that - if they're lucky enough to live on to tell about it.
That's interesting to know but I doubt both my wife who heard it too and I were having simultaneous strokes.
Static discharge.
Old macs and D/A dongles could have caused a converter mishap that shot a signal spike though your system.
you may get even more ideas if you post in the PC audio forum. I would guess that the reason for the pop will be evident someday.
that blew. They don't always smell, but usually do. They can be loud and it could be in a spot that won't change the sound much.

... some caps can short with a loud pop, and then recover. If that happens, the music keeps playing. Also, those caps may very well measure just fine using a meter, and will only fail when running at their normal voltage... and *then* only now and then. When I find evidence of a p/s problem with a tube piece, I like to just replace the p/s caps so I don't have to worry about leaving them on when I'm not around for a bit.

It could be a static discharge. Or a line transient that got through the power supply of the preamp. It could also be that the tube in the preamp has an intermittent crackle. It that is the case don't be surprised if you hear from it again.
