Here's what I wrote to Tommy:
"Got the USB to SPDIF converter hooked up to my DAC DAC and WOW what a difference. Super details and more smoothness. Nice! More details usually come with a bit of biting harshness, but not this time. Music sounds more realistic, so real sounding that it seems unreal.....guess I'm used to that 'recorded' sound. Anyway, I'm a happy camper."
I guess I should say I'm a VERY happy camper. No fatigue at higher volumes now. I did not realize how much my sound card was masking the music and giving it an 'edge'. This is quite an advance for my system's sound. Thank you so much!
