I know this might sound silly, but have you guys ran windows update, those of you who are getting screeching in YouTube? The YouTube screech has never happened  to me, but it was always when using Foobar or Jriver. I have always had the latest updates installed.    I'm surprised ASUS didn't...

I still cannot believe how much the sound has changed with the 10uF Silmic bypass, that dark black sound cant get enough of it.  I did a bit of research looking at datasheets of various OPAMP's, it seems implementation varies depending on which OPAMP used:   The AD797 within the datasheet...

Here is the pinout for both a dual or single OPAMP:                            DUAL                                                  SINGLE                  The longer leg is normally the positive, so the shorter leg will go to pin 4. Unless of course you have a bipolar capacitor then it...

I bypassed the LME49990 with 10uF 25V ELNA today. I am actually speechless on how much the sound has improved, there is more separation, detail and control in the lower frequency's. The background is black, the sound has become dark. Everything you stated in your earlier posts...

@pepopidas   I just read your experience from a few pages ago, it seems you have experimented with various OPAMPS and capacitors . I have 10uF 25V ELNA on the way, I will post impressions once I have installed them (cant wait).    I have only experience with 49720, 49710 and 49990, and stock...

@pelopidas Thanks for the info, I understand what you mean now, the capacitor is there to store a small amount of energy to ensure stability of the OPAMP. I am going to  try it on my LME49990 , I didn't see the picture yesterday on your post seems simple to install. I guess my only concern is...

Thanks for the info @pelopidas How do you bypass on them small LME49990, you put in between pins 4 & 7 on both OPAMPS? Or is there a better way to do it?
