My perspective I arrived a during my break is that we should not be afraid to engage in radical tip rolling. The acoustic-mechanical elements that makes the Lab 1 special are still there when you change the final delivery stage. Clearly there can be some such mods that will completely negate the effectiveness of those special elements and also those that are evolutionary and might work out well for the ears of the individual. There is only one way to find out. The key is that you can always go back to the original tips so there is no risk. Rather nothing ventured, nothing gained.
What I want to do differently now is lose the manic tip rolling and give certain sound signatures a chance. That is exactly what I am doing right now with a perhaps radical option: Comply Ts-400 foamies. It is way too early to reach any conclusions other than that these are the secure-fit comfort kings. That is a no-brainer. I am however also very much enjoying what I am hearing and I am going to give them a serious try over the next few days before going back to the original tips to compare.
Quite the coincidence! I also use the Comply Ts-400 as my tip of choice for my G2.5. I haven't yet tried them with my LAB, but will do so forthwith. Who knows???
