Does anyone know Grado's policy on selling replacement/spare parts for their headphones?

I've just read a couple threads about Headphile's custom headphones and was curious about how the HP and PS-1 drivers were obtained for these projects. I was always under the impression Grado did all their repairs in house and wasn't willing to send out replacement parts but if that was the case it would seem the only way to make a PS3000 would be to cannibalize a PS-1 which doesn't make a whole lot of sense.

Anyway I know this is kind of a random question but I'm a bit curious how this works.

Your impression is the way things are. I had my ps1s destroyed in the construction of the PS3000s, as did salty. He had his later converted to HP3000s, I so I have the only PS3000s in the world...

Interesting, you learn something new every day.

If you don't mind me asking what prompted you to go this route? Also are the housings left intact after the driver removal and would it be possible to put the drivers back in if you were so inclined?

I gave them to larry as part of the deal. I'm not sure what he did with them. I did it because I thought they sounded great, but the comfort and leakage left something to be desired. I'm much happier with the 3ks than I was with the ps1s. I'm contemplating doing it to my hp1s if I can't find a decent trade.
