It was one of the online musical instrument retailers, PMT. But, as I said, I think I was sent the Gen 2 in error although the description on their website said they were the ‘upgraded’ version it didn’t specifically state Gen 2. At that time though, they didn’t list a Gen 2 separately, so I suspect they may not have realised, possibly.Yep, seen those. Still feels like £700 is a bit much for Gen 1. What retailer was doing the Gen 2 for that price if you don't mind me asking.
I have been offered some Gen 1 mint condition units, 2nd hand, for £400. Which I am tempted by although I am still weary about the mmcx. It seems its unchanged from the new ones though and almost £600 between the 2nd hand gen 1 and the new gen 2 seems very steep.
Either way, I was lucky.
