I thought all Z7M2 are made in Thailand?I have listened to them for a short while, have had to work a lot so it was as a quick inbetween. They do sound alright, dark without veil and without sibilance, total blackness between tones very little resonance from the cups. It's the kind of sound I associate with high end audio gear, nothing is tinny. They sound meaty and not starved for power. Overall very good!
My pair was manufactured in Japan 2018 with serial nr 5196, contrary to later pairs made in Thailand. They seem to have made a detour through Russia as there was a Russian sticker on them. Probably from some overstock which trickled over to the EU to be sold at a reduced price, I feel lucky to have caught the deal
More impressions will follow!
Its the Z7 and Z1R thats made in their hand assembled factory in Japan.
