I actually don't know!! I had bought some random ass replacement tips for the tws I had like 6 years ago, and when I got the olinas I throw the replacement tips in with those, and they're both very similar. When I added the second filter, I figured I'd use the chance to tip roll to get a pair that fits nice and sounds good, and I found a nice pair but I can't tell if they're stock tips or not. I want to say they're aftermarket because they seem softer than the stock ones, but I really can't tell anymore.

I got the SMSL c200 sitting on my desk, I'll probably plug the olinas in eventually to give it a shot.

I do want to get the final E tips, I've had the e500s on my list at the start but got the quarks instead. Probably should've just gotten the e500 at the time. The narrow bore would really help to alleviate my concerns about clogging too.

Are you rocking double filters? Or are the E tips enough to get the bass where you like it and tame the treble? I found the treble to be ever so slightly hot with only 1 filter.
