I've personally found the La Bella 2001's MT trebles to be warm, sweet and colorful. I suspect their thick diameter yet low tension compared to other string brands contributes to this. These are my personal favorites so far and they are quite affordable.
I have a 10ph set that I have yet to try, but based one what some have said, I expect it to be higher tension, clearer, brighter and more projecting.
