I just received the clock and I am now ready for installation :-) Do you know if it matters what kind of cable I use to connect the the clock to the STX? Will any copper wire work? Did you also remove these two small caps and the small resistor? Marked red in this picture:  I am not sure if...

WeirdChild: Did you upgrade to the Audio-gd? If so what version did you buy? TCXO version?  Where is the easiest place to connect the power on the Audio-gd?

Hello pelopidas,   Awesome work! Do you run 3x 49990 with the silmics on your card? Or is it some other combination on the buffers and I/V? I just recently did my first solder and want to try this mod. I'm running 3x49990s DIP8-adapter on my essence stx now. I guess I can just copy...

Burson Audio, Does the 0.1uf MKP capacitors come with if you buy the V5 Op-Amps? Do you have a higher resolution picture of the soldering? 

Running Schiit modi and vali with the HE-400. It is great, but on high volume the highs get tearing for my ears, but I've found that using the forward config for foobar2000 makes it really lively so I don't up the volume as much...

Anyone have any thoughts on how it would pair With HE-400?

I got my replacement couple of days ago as well. They refunded my shipping all the way from Norway. Very pleased with their customer service.

I am looking forward to hearing what you have to say about the 49990! Did you order from frugalphile@ebay as well? What headphones are you using with your STX?

Could you provide a picture of the yellow and grayish/white support? I bought mine 2 weeks ago, and I want to make sure. Mine I would say is more white/yellow.

Making the sound more neutral, the bass isn't as prominent, the bass is still very good though, it has a sweeter edge to it. I have a feeling the LME49990 is a better long term solution. I switched my headphones earpads as well from pleather to velour now, and I think I prefer the LME49990...

Tried with three DUAL SOIC LME49990 DIP8 ADAPTER that I got in the mail from frugalphile, but to me I feel like the standard opams with Dolby enabled sound better or little more clean? With the 49990 i feel they are better with no Dolby enabled, kinda weird.

I got my He-400 rev 3, one week ago and I like them, but as everyone else the highs might be to much on some songs, but I've since done some tweaking with my DAC and EQ and I feel that they sound super. Which songs would you recommend for testing for this audible high peak?

I got three DUAL SOIC LME49990 DIP8 ADAPTER in the mail here the other day, and I'm wondering if you guys would exchange all 3 opamps for those if you were using a HE-400 headphone? Or would you recommend another combo? Really loving them so far, mine is rev3, and they sounded very bright at...
