Ya you will have less of a reason for upgradetitus once you hear this dac and your HA-S500. I look forward to read how you hear your tunes once you get this DAC. You thought your HA-S500 sound good now. I am willing to bet you. You will hear them in a new level once you hear it with this DAC. The HA-S500 does sound better with better sounding hardware. Sound unbelievably great on my Fire Phoenix. And on my Bravo amp. I haven't tried it yet with the ELE dac but there is no possible way it won't sound right with it. I will post a little turkey thanksgiving post on the HA-S500 thread tomorrow..
$18. And it makes everything you hear from your computer sound very great. Completely worth the cash and thensome.
When you get a chance, let me know how it makes those xba3's of yours sound
