    Unix and its variations.....<br />Music most definately...it sooth the beast in us all<br />Currently trying to pickup amp making for fun
  1. Grado Labs SR-80 How many hours does the can have already?
  2. Burn in the can more..... Try to move the can back abit from your head....position it back of the ear rather than the front of the ear. Its just a small move.U'd have to find that right spot when u feel the headache... Thats wad i'll do... sometimes its just the head not used to the clamping feeling of the cans
  3. Interested with the grado SR80. May i start at $100
  4. how abt these http://sg.farnell.com/jsp/endecaSearch/par...SKU=3018714&N=0 only bummer is u have to get 10 peices
  5. http://www.sistic.com.sg/SOPApp/SOPPortal/...qI50yds.PjtsJFM
  6. xchagg..very nice!!! mine still in progress
  7. hi guys opa2134 - lm6171 = no distortion....but occil abit then fades off...the sound continues nicely opa2134 + lm6171 = distortion opa2228 - lm6171 = distortion opa2228 left side = ok opa2228 right side = ok opa2228 + lm6171 = distortion opa2228 left side + lm6171= ok opa2228 right side + lm6171 = ok will double check the soldering tomorrow..sigh
  8. just in case i get a grado....i might need it or i can justify a grado to fill it up 1 for me
  9. Finish off the cmoy2 but getting problem with oscillation. Reading the thread i've found that starushz and alvin 2038 also having the same problem. I'm using opa2228 also. ordered opa2134 to test whether its the ic thats having the prob. Funny thing is unless i on off/plug out HP, the cmoy2 sounds great. Put it back and i'll get hissing, occillation and a bunch of other noise
  10. i've put it back to gain 6 and after awhile realised what was the prob. the cable attached to the croc clips were loose with only a few strand attached.wondered why it didn't come off completely.anyway its in the hammond box already until i reliased that the i/o stereo conn is to big for the box.so i'll have to wait till weekend for a trip to slt.
  11. Sony old product are good...same goes to many other brand...when they move their production to other country due to cost...quality is affected.....then due to competition, cut cost cut corner...u all know the story
  12. Hi. You should try these value to reduce the bass rolloff. R1: 10 R2: 20k R3: 20k R4: 20k R5: 10 R6: 20k R7: 20k R8: 20k hi jason tried it but it sounded funny....i get weezing sound when i touch any of the resistor.the resistor is mounted on the socket so i can play around with gain and such. going to resolder the wires with those multi strand wires. was using the single core type and it seem to come off 1 by 1. progress abit slow though
  13. its been an issue thruout the world and sony haven even raised a finger
  14. same..i ordered..next day called no stock need to wait 3-5 days but other stuff arrived on the next day i ordered..so its ok
  15. Got mine up to go on the first try!! But there's too much bass...roll off the cliff soundstage sounds narrow resistor i change the value abit 10 = r1/r5 100k = r2/r6 20k = r3/r7 20k = r4/r8 20k = r9/r10 are these the problems? anyway i can improve it? thanks
