Quote: Not sure where you picked up your 49990. However, the PCB should have it on there as to which way it should be oriented when putting the op-amp into your card. The little dot on op-amp that you took out, it should face in the same direction.

I've been impressed daily by my Klipsch ProMedia 2.1.   http://www.klipsch.com/promedia-2-1-computer-speakers

Quote:     I just switched from LME49720 to LME49990...I'm picking up my jaw from the ground still...I have the say the biggest difference is for me was the bass. It's tighter, more defined? The mids to highs are more smoothed compared to the LME49720. I actually turned OFF my EQ that I...

What are some good music tunes to fully immerse yourself into music and really show off your cans? I don't care what genre of music, but just looking for something to come back and say "wow that was amazing". Right now, I'm using Beyer DT-990 600ohm powered by an STX. Maybe some upbeat jazz? Any...

Quote: I was thinking the same thing when I first got my Beyer 990 600ohm. Check out my custom EQ generator for Xonar Audio Center to help boost the low end.    http://www.head-fi.org/t/643967/headphone-eq-generator-for-xonar-audio-center

Quote: Not sure with everyone else, but I'm using the older version by Jeroen Breebaart on his website...there is a free VST bundle that has some goodies. I'm sure the newer version is better, but at least you can see what is out there.    http://www.jeroenbreebaart.com/audio_vst_jb.htm

Quote: The first spreadsheet is the one that you want to focus on if you're looking to create your own custom EQ after determining the flat line. This is where I'm looking for feedback on the Google Spreadsheet I made. The second spreadsheet was my weak attempt in mapping my headphones freq...

Quote: I did some testing with this. I uninstalled the program, reboot, reinstalled again, reboot, did the configurator, made sure of all defaults and tested in Windows Media Player.   When running the Configurator I had 4 connectors available: Speakers - High Definition Audio Device...

I downloaded this and I've tried editing the default config file with increase/decreasing the preamp volume and making sure to save the file. However, I'm not noticing any difference in music playback. I'm not sure if this matters, but I'm using an ASUS STX soundcard and not onboard. This...

Quote: Thanks for this. Appreciate the consideration!   Has anyone used my chart to help them create a graph? I haven't had any feedback or anyone post problems? Either everyone that may have used this found it to be useful or didn't use it at all? Anyone?

Quote: This is a bit harder than expected...problem being ASUS Xonar Audio Center EQ only supports 10 data points where as from Headphone.com I have 29 data points. I wish the software would support more than 10 data points so I can have better accuracy.    I uploaded a new...

Quote: Do you know where I could get data points for various headphones? Headphone.com only gives a graph without the actual data points. Any input would be helpful.
