Thanks for replying.The only upgrades are to get the 1.1 tuning kit and perhaps to upgrade to a VIVO cable, which has a smoother, more resolving sound and a larger soundstage.
Looking at the photos VIVO Cable looks like same thickness and stiffness than the EFO v1 stock ones. Am I wrong?
What about total price of upgrading to v1.1 and the VIVO cables?
Additionally, is it worth the VOCE Electrostat Ear Pads?
Thanks for helping me.
Cheers
