Grado PS1000 Owner's List
Proud owner of #239 here. Got them used from head-fier in NZ. Recabled with Moon Audio Black Dragon. Finish on mine is good but not perfect. Have a few tiny black speck (you have to look for them). They have a matt to satin finish. Sonically I love them. I listen to them every night before...- wolf18t

Grado PS-1000 initial impressions
My personnal experience fit with Tamahome77. Out of the box the highs were a bit too hot and the bass more prominent. But with burn-in the highs and bass calm down a little, with less sibilance and the mids seems more refined. They are getting better that's for sure but they're still not...- wolf18t

eXStata DIY Electrostatic Amp for Intermediate DIYers
Count me in the seriously interested builders crowd. My only problem is that I don't have any stats. Very handy for the final QC test. But that shouldn't be a problem for very long. One thing I would need before getting into the project is find info of what are the bias standard and what...- wolf18t

Are the HD650's forgiving?
In my experience the HD-650 were the most forgiving headphones I heard. And I heard them with many different amps (SS, hybrid and tubes). Some amps may make them sound more detailed but never harsh. More forgiving than them you will have to insert pillows between your ears and headphone...- wolf18t

Chassis source in the US?
There was once diyenclosures.com. But he is just liquidating his very limited remaining stock now. Other than that there is the nice Dissipator series from Teko Enclosures but only 1U height. The 19" rack series still look good.- wolf18t

Stacker II- Progress? Availability?
I've just read the entire thread. Look very promising. Totem pole input gain stage. 100V to 150V adjustable plate voltage per triode section (200V to 300V B+). Dual triode noval and octal tubes support. A tube roller dream! The BJT output buffer seems, to me, a bit complexe (reference...- wolf18t

Stacker II- Progress? Availability?
Without seeing schematics, anyone know what are the design features that set it apart from the SOHA/SOHA II, Millet Hybrid and Akaido? Higher B+ and CCS bias? DC coupled? DRPP or SRPP or SRSE? BJT or MOSFET buffer? How many mA or Watt into class A? What tube family will be compatible...- wolf18t

Hmmmm! - New Single-ended Class A - Looks nice!

I never heard a stock PS1000 so I can't compare. One thing for sure I'm very happy. It took many life privations to afford them, but they are well worth it to me. (I think we need to edit and add a new PS1000 smile...)- wolf18t
