Otari before re lapping, you can see quite asymmetrical wear pattern.

I went to Audio connection last week and had a listen to these headphones, the price was around $85000 Australian. Yes that is right $85000. What do you get for that money. Well it did sound very good. What brand you Ask, i think they are Sennheiser's Orpheus. Its probably worth it because it does have a volume control. I am taking orders.

I had a 4 STLX Copper caps laying around so i put them to good use. Out went the 4 Jupiter Copper foil caps and i installed 4 of these caps. Why because i could. Now it is just different, but excellent, basically its name your poison, but as i said before its no longer a cheap rebuild.

Probably easier than a cd  player Steve  .  Best to start with a better mouse trap . Begin with amps that  have good power supplies   .  I prefer fet inputs with bipolar  outputs .
   The Staxes have quality  in all the main areas  ,its just a matter of replacing the cheap  mylar caps with  top quality caps .  I am beginning with caps from my parts box  to get a baseline for improvements then may try some jupiters etc . So far results have been very encouraging.  The areas for further improvement  i see, seem to align with the key areas that Jupiters and Duelunds  are good at .  I may need some technical advice  with  input filtering    at some stage but for now  keeping the design mostly stock apart from  reducing the bypass caps from 1uf to a quality .01uf ..
   I have modded the DA100s and these are almost  the same  but only 50w  so lessons learned  form the DA100 willl be used on these .
