Other than upgrading the RCA cables what else do you guys recomend for me to make the experience better? I have not modded the stx yet and everything is stock.
The Lehmann is a fine amp and a great match for your HD650.
1. I'm not familiar with the Xonar, but unless you hear some distortion or clipping, you should set the computer output to near maximum for best signal-to-noise ratio.
2. Whatever setting that allows you to use the Lehmann volume control near its midpoint or higher. This is where the tracking error of the pot is minimized.
3. Not much else to do as the amp is fairly bullet-proof.
4. I'm not a believer in burn-in or break-in making huge differences in electronics and have found no change in my Lehmann over time. Just enjoy right out of the box.
Again, I know very little about the quality of your sound card, but for PC audio, I use the S/PDIF output of the computer into a DAC then into my headphone amp. Others can give you some advise on how the Xonar compares to an entry level DAC.
