    I'm a bit late on this one since the Ara seemed to steal the thunder from the 2020 update to the Andromeda. Physically the dimensions are unchanged, so those with fitment issues with the nozzles being too shallow with the OG Andromeda won't find this any better. The only change that I've noticed from the OG is bore opening is a grill instead of three holes.

    I will keep the subjective impressions short. While the OG Andromeda (without much tweaking and from a near zero ohm source) has a slight V-shape, the Andromeda 2020 is a dark sounding IEM. Actually quite a bit darker than the measurements below would indicate. The highs up top do sound a bit more refined, but I am not sure if this is via the tweaks since the OG Andromeda (applied to Solaris), or a function of the FR differences (more lows and less highs). In a nutshell, the 2020 Andromeda is a OG Andromeda with a darker tone and smoother highs.

    See general measurement notes before digesting the plots: http://www.superbestaudiofriends.org/index.php?threads/note-on-iem-measurements-changelog.2153/ Any who allow a single or handful of measurements to define sound quality will be immediately banned from SBAF.

    Here is the impedance curve of the Andromeda 2020. It's very similar to the OG Andromeda's curve.

    Here are the distortion characteristics which are very similar to the OG Andromeda.

    If memory serves, you preferred the original Andromeda from sources with a Zout of 3-4 ohms. Is the Andro 2020 correspondingly darker even with higher Zout sources? If so, does the darker sound of the Andro 2020 amount to a significant departure from the original? And do the more refined highs make for less sparkle, given the FR variations between 6 and 8K on the second plot? I'm sorry for the multiple questions.

    The original Andromeda I either preferred with neutral-bright sources (Chord Mojo) or slightly higher Zout with warmer sources (Sony ZX2 or Pixel XL) to tone down the lows in relation to the highs while running a tip with a filter (Comply foam with filter) or a tip that recessed the highs.

    Andromeda 2020 is slightly different. I do not feel a need to tame the brightness at all. The sources I would use are still the same: neutral-bright sources (Chord Mojo) or slightly higher Zout with warmer sources (Sony ZX2 or Pixel XL). Even then it's a bit dark / bassy when I'm using the Final silicone tips.

    Is the channel imbalance in the bass audible?

    I didn't think so, but I'm pretty deaf in terms of imbalance in the bass once it gets below 60Hz. The bass differential could be a seal issue on the measurement rig. I didn't mess with the placement on the coupler much.

    In this video from Jude at Head-Fi:

    at 9:25 he comments how in his measurements, the L/R channel matching was some of the best he'd ever seen.
