Hi there. I have an iBasso D10, and a Sennheiser IE8. Currently I have two options of upgrading. One is get a 5.5G iMod, then get the copper+silver cryo dock with black gate capacitors, or the other is to get the iRiver iHP-120/140 or the ones modded with 32/64GB CF cards and get an optical cable.
Will those of you who have listened to both please give me some input?
