Mines from Jaben too. and I can relate with ur experience
In my case, I would clean and wash my ear AND spinfit if I want best full sound with very good impact in bass and wide stereo. by cleaning it gave the best fit and sit quite shallow i my ear (e80). this has been my preference for months.
but
if I wanted to hear complex music or very good recordings, I tested some mono noise while push spinfit all way in and find balance in left right.this way the stereo separation became like crossfeed effect when listening to music. IMO, with my iem I can get the increased bass speed and better layering, sub bass sits behind all the instruments and mid bass / mid capture a lot of micro details and superb timbre. but the staging get kinda smaller (but quite accurate), with increased depth and extensions.
YMMV though...

I feel that the Spinfits insert deeper and give a better seal than all of the other silicone tips I've tried. Mine are the Jaben
I wear them with my iems over ear as that allows the unique rotation of the tips to point directly to my eardrums.
I wonder what you do when you insert the tips. I make a chewing motion to work them deeper and I moisten them before putting them in.
Maybe custom sleeves might be an option for you. I'm just about to embark on this myself.
