I've had mine since new in '76. A few years ago I re-cabled them with Mogami and damped them with two layers of felt and sealed them up with monkey snot (rope caulk). A huge improvement or so I thought. Recently I picked up a pair of virtually identical YH-1's. In comparing the 2 the originals were much more open and airy, but lacked the bass of the modified pair. Even more recently I bought some Stax which really show the shortcomings of my HP-1's. The detail and high-end was just not as good as it should/could be. Since the re-cabling I've had to open them up and repair broken wires several times. The lack of proper strain relief being the culprit. Said monkey snot making the job a PITA.
This time I hope is the last time I'll have to repair a broken wire. With the drivers removed and the baffles in place and working through my drill index 1 step at a time I was able to enlarge the hole and recenter it as I went to add 3.5mm panel jacks. While I was at it removed all the old monkey snot opening them up again as orthos should be. (Thanks again to Wualta for reminding me of that). I went to just one layer of felt and sealed the baffle with gaskets I cut from a silicone baking pad. I also added treble dots on the back of the drivers. So far I just gave them a quick functional check listening. My receiver has a decidedly meh headphone section so more listening won't tell me much. I'm actually excited to go to work tomorrow so I can try them with my HP amp. Hoping for goodness.
