Who started the headphone line? Joe or John? And what year was it when the headphones were first sold by Grado and how did it look?

1989, Joseph Grado rolled out the HP1000.

A little curious, but considering that the Grado blogs are nowhere to be found. Would it be possible to revisit this history segment?

I’m pretty curious when it comes to learning more about this companies history, considering there are a lot of limited edition, headphones released after 2012, so if you if you can do it, I’d like that please.

Also just got a pair of 50th anniversary 325is a week ago.

Curious if anyone could help with a price check on a pair of HP1s (with polarity switch) in 2024. Thanks in advance.

Grado brand is either you love it or hate it. Sometimes they sound good, some times they are no different than any other mid to high range headphones. If you can spend a bit more, go with higher end like Sennheiser or Audeze headphones.

I'm only saying the two are not the same...

The time's about right... it is my pleasure to introduce to Head-Fi the “Primo DH-40”, taken of a Nakamichi SP-7:

(It isn't as perfect as the HP 1000's DH-57 but like I said, they still are close brothers in sound.)

They could make a good “faux HP 1000” mod, drivers are easy to extract and cheap at 100$ on eBay.

I still have my SP-7 but plan to sell. I transplanted to Grado cups but wasnt impressed because didnt have as good bass extension, so reverterted to stock. Treble was perhaps slightly smoother than SR60 but otherwise pretty similar aside from bass extension difference, imo. It was a neat experiment to try as a Grado fan. fyi, Ive only kept Grado PS500e and instead have been making my own supras with off the shelf drivers.
