Kees sold me his Sennheiser HE60/HEV70, in a partial trade for my Edition 9 and some cash from me.
Even though he only had part of the sale as cash, he shipped the Senns immediately, 12-24 hours before I could ship the Edition 9 that I offered up as part of the trade. Some people might see it the other way around, but it was his deal and he could have waited till the full payment arrived. So, I appreciated it.
While I got the Senns in yesterday with no sound coming out of the right side (with either of my amps), I didn't panic, knowing they just needed to be run a bit to wake up after an international flight and extreme changes in temperature and humidity. In 5 minutes there was faint sound from the right, and even more sound the longer it was running. After a full night hooked up to the SRM-1 Mk2 the HE60 was working great with no channel imbalance! I have a 110v PSU on order from Sennheiser, that should ship to me by the end of next week, but I am certain that I will find the HEV70 works fine as well. I could always cut the 230v wallwart cable cable and solder the connector to a 24v PSU that I have here, but I am a patient guy.
Communication was good (except I don't know if you like the 9's), and everything was as described and packed well. I would be happy to deal with Kees again in the future.
I CALL DIBS ON THE EDITION 9 IF YOU DECIDE TO SELL THEM LATER (sequential serial number to my other pair)!
