I am using the DX3pro in the high gain +9db setting, however a difference in my setup might be that I have balanced cables on my HD 6XX w/a converter to 1/4" SE. I believe I was in the range of -6 to -8db volume setting, but my unit only goes to +0 as the highest volume. I am uncertain if using balanced cables here changes things..bought the adapter b/c i didn't want to keep changing from balanced to the stock cable.
THW,
re: equalizer SW, i am only using the USB connection direct to the DAC (w/the over $9000 USB cable--Microsoft Certified™ that Amir made especially for me! ) w/Foobar 2k set to WINASPI event, sound volume in windows is 100% when using connected DAC. I did have to install the Topping SW into windows 7 for it to recognize DX3pro.
...confession...bought the Schiit USB PYST cable when i got the Jotunheim and Modi Multibit. deep regrets here, but the cable was soooo purty...
