  1. bk version sounds similar to the standard SR-009, maybe a little bit more distant and tighter bass due to the new thicker earpads.
  2. I have made a t8k input stage board for my bh,with a little bit tweaking,they've been working for 4 months,and T2 input stage can work fine as well. ?
  3. chinese bhse from taobao jr audio。。。
  4. rare and expensive audio equipments are popular in china and people are willing to own a machine like singlepower as their audio collection,and I'm sure vertek now is ready for the copy of headamp's bhse.
  5. the jr audio on taobao? i know you,you're a fan of spritzer.
  6. ‘FOTM’,what's the meaning of that?
  7. http://webcache.googleusercontent.com/search?q=cache:_8k5_bjQSfUJ:stax.xsrv.jp/products/sr-009s/+&cd=13&hl=en&ct=clnk&gl=hu SR-009s
  8. I try 02N120P as output fets,this time fr(-3db) can run up to 74Khz,and (-6db) about 114Khz. circuit works much better now.
  9. it's good to see more es amp designs. The thd+n is really low about 0.005% fr(-3db)only reach about 11.6Khz and -6db at 19.9Khz from multisim ac analysis when gain is set at 46db,higher the gain the lower fr will be,not sure the circuit works properly ,btw it's easy to run kgsshv fr(-3db)over 110khz or even higher,and 2nd harmonic distortion of -79db and 3rd harmonic distortion of -61db at 1Khz
  10. rumor from edifier dealer said that sr-009s is ready to launch
