Guys I wish I could tell you these notes of mine are accurate, and they are but at the time i probably thought I would recall exactly what i did.
IF I get around to opening them both up again I will post on it. I know for sure the HP-50 notes are not right.
- The HP-50 notes say I used the yellow rockwooly type biscuits from the Stax Sr-40, but if I recall they took too much out.
The Hp-50 I found it hard , at least with the billions of materials I tried, to get the balance between the deeper bass and maintaining highs with the gorgeous mid areas.
It was as though it got close to the point, but the point between too much and too little was a very small area to grab ahold of.
- The HP-1 mods I have listed ( closest I have to the TDS-5 ) uses, according to the notes, 0.2 grams Angel Hair per side in cup rears and direct Arctic Bamboo 55mm damper. The Angel Hair deals with stray sound and trebles, and expands in place to hold the damping disc tight to the driver rear. Stock felt damping around the perimeter is intact. the Arctic Cotton is a bit thicker and probably brings out the highs more ( I know it does ) than the Arctic Bamboo.
Just my experience though, really looking forward to what you guys come up with.
Thanks for posting these things up it's got my enthusiasm back !
And the Unipolars, really curious to see how that goes, maybe you have to reduce the pad opening down to 10mm holes
