Headphoneus Supremus
The 18S I already have and absolutely love - they teased another two releases in their video though, those are the ones I was referring tohmmmm, what new 64 releases? the 18's? Also curious about Thummim vs Sultan for the fun side of things.
On Thummim vs Sultan - they aren’t too dissimilar, the thummim is a little bolder and more exaggerated with less lower treble but better extension, and larger staging
the thing about the W2 is it does have that natural tuning but the midrange is really pushed quite forward, so while it sounds wet and inviting, I end up being unable to really experience that staging that you mention. Seems super vocal dominant, and places the mids in front of both the bass and the treble. Overall, big mehConsidering darker/warmer sound nature of Thummim, you will probably like pair up with a brighter tuned S1, since W1/W2 are smoother and more naturally tuned (typical L&P). In terms of technical performance, W1 and S1 are close enough, while W2 is noticeable step forward with a bigger soundstage and much lower noise floor. W2 technical performance is nearly the same as Cobalt, and tonality similar as well. But Cobalt has a little different signature, lacks balanced and no other bells'n'whistles (no volume control, no EQ presets, etc). One thing that I can't live without anymore is a volume control on these usb dac/amp dongles. Unless you go into the app and adjust the volume from there, changing the volume on your smartphone using side buttons has no precision. Having volume buttons on these dongles helps with micro-adjustment of the volume in smaller steps.
Romi Audio dac/amp looks interesting, aside from no volume or no eq. But the power output is a little less than W1/W2, which is still OK for IEMs. But one red flag is 200mA playback current. This will cause you problems with iPhones because they limit external devices to 100mA, and with Android phones will cause a higher battery drain.
