Great stuff @gadgetgod - Thank you for the time spent on this review, and for highlighting some very articulate points about the tuning. We also appreciate the vivid and rich photography to go along with it. I'm starting to see alot of M7 pairings with the 600, and it seems to be for all the reasons you mentioned. Well done!

Thanks for your kind words @ericpalonen !!

Is it worth the jump from these to unique melody mest mk2? In terms of mostly technical performance like soundstage, imaging and details.

@gourab1995 I personally didn't like Mest Mk2. Although I would say you will find the soundstage more spacious and instrument separation also better on the Mest MK2.
