Head-Fier
Here are a few recommendations based on my personal experiences:
Dunu Luna: a bit softer presentation on the vocals, highly detailed and you will hear every inflection. Excellent all rounder as well. The Luna does need a higher volume to sound its best (to get the bass) but still well within what your phone can produce, and a good match with the Dragonfly Red ( I have one as well). For this IEM I also recommend the Azla SednaEarFitShort ear tips ( on amazon). You can get this from MusicTeck.com (Andrew) at a discount which makes it a great deal and way under your limit.
Campfire Andromeda: a great IEM. It is known for its top end and I use this all the time when I used to go to the gym for both music and podcasts. Audio64 carries this and they will provide a 10% discount. An excellent baseline IEM.
Vision Ears VE-8. This will go over $2k. You would purchase this from VE directly (They are made in Germany and have top notch customer service). That will save you the Vat Tax and make the total cost around $2300 or less. This is one of the best IEM’s available though, and is custom only. It does vocals really well and everything else including the bass.
The VE-8 will not be as forgiving as the Luna on bad recordings. I do feel it is better overall, and it also sounds great at any volume level.
That is a very short list and hopefully will be of value to you. Tks.
Great list, anything beryllium-related does work wonders on bass.
