Some discoveries for me:
Rose Mini6 (improved version):
#1 Plugging in and out with the MMCX works now fine for me. No BA's dies! Improvement - check!
#2a Nozzle with additional metal tube - no idea, why they made this. My former tips don't fit anymore. It is now an in between diameter size. The tube from my left unit detached with the first trial putting a tip on it. Only glued. Improvement - no!
#2b Nozzle now without a mounted filter at the top end but open and inserted with a very flimsy loose type of meshwork. Likely only to prevent to get something in the IEM rather than a tuning filter - Improvement - no! Because, I do not get the sound quality I remember with the first version and that is really a pity. Don't get me wrong. It is not a bad listening at all but I don't get the WOW factor with the Mini6 anymore.
...But it is all relative (by such a big margin sometimes)…
...because I did a short comparison session with my 4 recent favorites,
Rose Mini6, Mini4, MT100 (Planar), Audbos P4 - starting at 7 p.m..
All of the mentioned sounded different in its balanced characteristics but all like angels to my ears with all a good amount of bass and all notes so unbelievable smooth. A pure joy.
I stopped listening and watched TV for two hours, than I started the second session of the day at 10 p.m. by using the same equipment.
And this is the next
discovery...all sounded like almost completely different as compared to the earlier session of the same day. No forward bass anymore, not a smooth like angels heaven sound from all of than (but of course still good - very good).
This was quite a frightening finding to me. That you can hear such big differences with one earphone but at different times. I already recognized this effect earlier but not by this value.
Conclusion for me: Hardware (setting) remained very very likely
the same but the main factor of the difference was just me and my physiology and/or brain (mood, mind, memorization) or whatever...
