Got the Shakes
500+ Head-Fier
Please try flac files with the OPO outputing to the E07K through USB and let us know your thoughts. I'm still thinking whether to get the E07K/E18 myself...but the headphone out on the OPO is so good already I'm wondering whether the cost (less of a factor with the E07K) and the additional bulk (a bigger factor for me) is worthwhile for the improvement in quality.
I can do that, but it's going to be a few days. Leaving for a wedding tonight after work and won't be back until Sunday.
