I own the Andromedas, also 4 years old or so, and going above them with any IEM is incremental. For example, 64 Audio Fourte is not better in all areas. In fact, the Andromeda is probably better in the upper mids/treble though a bit different. And the dd bass of the Fourte is not always more impactful or tighter than the Andromeda. It is better overall, but incrementally. The Traillii is better in every area, but that is allot more money. I personally prefer the Luna to the Andromeda if you like softer highs and you can get deals on that from Andrew at MusicTeck. But in the end, it is still only an incremental change though this would be well below 2k.I have a pair of Andromedas about 4 years old so not the 2020s..... I like them alot but periodically wonder if there is something that much better out there for under 2k.... Do the Senns or MESTs MkIIs blow these away or is it as I suspect incremental. If I had to fault anything on the Andros to my taste the soundstage isnt that big.... but that could just be IEMs in general. My big cans are HE-Xs as a point of reference.... and their stage is huge in comparison. Thanks for any thoughts.
( I would also suggest staying away from JH Audio. I feel the Andromeda is better ).
If you want something better overall and around 2K I might suggest going for HP’s. They should be more than an incremental improvement if you can drive them. Maybe a used Focal Utopia or Empyrean as a couple of examples. Probably over 2k though, but they are TOTL’s in the HP area. There are many others you can look into. Good luck.
