Hi Fred. Got mine today. Looks perfect. Thanks! Cheers Rolf

Hello compor, i am using this card too. Operatingsystem WIN7 or Ubuntu10.0x Before installation i changed the OPA to 49720. Never compared to the installed one. Used with headphone Panasonic RP-HT360, 40 Ohm, the max. volume is very loud. Sounds great. But with Beyer DT-990, 300 Ohm...
