Went on a tip-rolling spree in order to prevent myself from spending more money on IEMs lol. Here are some random impressions
Spinfit CP100s are just a solid silicone eartip that doesn't really standout in any aspect for me but are generally better than a lot of the OEM tips that I get.
Spinfit CP155s were bought out of necessity for the gargantuan Moondrop Variation nozzles but do a good job of seemingly increasing bass but are a little uncomfortable since the nozzle is a bit long and the end is slightly more pointy than other Spinfits.
Spinfit W1s are quite nice in terms of seemingly widening out the sound stage but also have some fit issues for me potentially due to the rather malleable nozzle. The "sticky" nature of the silicone does a good job to maintain seal but the whole thing does not seem to hold its shape and position as well as other tips.
Final Audio Type Es are just great all-round for my ears. Very comfortable with an effect of making the midrange just so nice and taking the edge off the treble.
Campfire Marshmallow tips are very, very squishy and quite comfortable. Hard to make a definitive statement on their effect on sound at this point in time though.
Will be looking at purchasing AZLA SednaEarfit XELASTEC, Dunu S&S and a pair of Chus just for Spring tips which is hilariously the most economic and quickest way to get them.
