What did the tips that you changed from look like? Stock tips are black, soft, thin single flanges or comply tips.
To use an image I would say that auvios sounded like a thin, thin glass between me and the music. Comply tips put me and the music in a large, sound isolated room.
Glad that you tried out the foamies for everyone here. I don't like and wouldn't use them anyway so you wouldn't get that compro from me lol.
I still dream about UERM bass on the RAM album. The imaging of the low end was a revelation. The closest low end imaging to it that I've heard was the F111 but it wasn't nearly as characteristically satisfying for me.
