Love my Yamahas as well. Glad you dig em. These don't get the attention of the big names but they deserve it. Mine gets used all the time as they are attached to one of my main desktops.
Even with my X1 and SRH1540 right next to em they get their turn with music in my rotation..I hope Yamaha makes a full sized open can one of these days. If so I will be in line to get one.
So a little update on the V aging. These amp really well and my thoughts of how BAs not amping as well as Dynamics has changed somewhat because of the aging. Out of the ICON dac it becomes a new beast of an earphone. Them smooth lushious mids are all over your face. These are a vocal lovers iem for certain. The forward mids makes vocals shine like crazy..
