Great post and glad to hear you are impressed with both QP2R and Noble IEMs. Give everything some more time to jell and I am sure you will be even more impressed as is usually the case with burn in and settling of the gear.
I really don't have much experience with IEMs simply because I never found them comfortable before but I am sure they have also come a long way and perhaps it is time to give them another try.
Enjoy!
