Hi, I'm new to high quality audio, and equipment is no exception. I have Yuin G1A headphones and just recently received the Fiio E10 usb dac/amp. I seem to have a problem. On Windows 7, I changed the driver settings - 24/96 audio should be working now. But I've listened to classical and jazz flacs in both 16/44 and 24/96 and can't tell the difference. My headphones have had 150 hours of burn-in without an amp, but should I expect audible improvement with burning in the e10? Or will my inexperienced ears just never appreciate the $220 upgrade from my $20 GE headphones? Also, the volume buttons on my laptop still work when the e10 is plugged in (default device, of course). Is that normal? Sorry for the newbieness. I hope I didn't duplicate.
