My MW10 came in the mail today (I'd share a photo but I lack the permissions) Some "off the cuff" early impressions: These are easily the most beautiful IEMs I've ever owned. Unfortunately I don't know how helpful my impressions will be as I've never spent any significant time with the OG Andromeda and haven't heard the 2020 in a few months. Suffice to say the MW10 sound amazing...but they are very very close to what I remember the 2020 sounding like. At this point I would tentatively say that all my impressions of the 2020 basically apply here (however it's early days and I may have more to say on this later). Regarding the question of whether the MW10 has the "missing" treble sparkle of the 2020 I can't confirm or deny absolutely without listening to the 2020 (or the OG) again. That said it's noteworthy that, coming from 2.5 straight weeks with the MEST, which is known for its highs, sparkle and air, I don't find anything lacking or suffocating with the MW10 Andromeda. It could very well be that the MW10 takes the lows and mids of the 2020 and combines it with the relative brightness and treble profile of the OG...but I would have to hear the 2020 again to verify this for sure.
