Now, you turn on music with heavy bass impact (techno, rap, etc) and it sounds like the driver is about to pop.

That's an EXTREME of what the HF2s sound like to me, but its that same "type" of sound.
Sorry, that description makes no sense to me at all.

However, it sounds like you've deduced the issue. "B-stock" was clearly stated by Todd to be those Grados that were returned for one defect or another during the HF-2 sales. That said, I'm sure he or Grado will stand behind it and repair it. I almost wonder if it's a variaton of the infamous Grado grackle, except your statement that the driver is cutting out sometimes seems more serious.

That's pretty much why I got my degree in computer science instead of communications. lol

Basically, it's the sound of too much power going to the driver and causing the driver itself to over-extend.

I've never heard of "grado grackle", but I've read here about this type of thing maybe being caused by having a hair on the driver? Does this happen to Grados? If so, what can I do to make sure that's not what it is?

Besides the issue I've mentioned, the cans sound GREAT and I'm going to miss them if I have to send them off for repair.

Look about 1/4 down the page for "Fixing the Rattle Noise in the Diaphragm."

Speaking of communications issues, I had one with "grackle." Grackles are the blackbirds in my back yard. It's Grado grattle.

Thanks for the link; I tried the fix mentioned (using the "breathe in" method) and it still did not work. I did not want to take the driver apart since its still under warranty through Grado.

I ended up sending them to Grado and they confirmed an issue with the left driver and are doing repairs now.
