However, my music comes mostly from Pandora and iTunes. If I upgrade to Sierra-1, will the speakers be overkill for my music source?
Not at all. A few suggestions, set ITunes to load lossless for best quality.
In addition to Pandora, I use MOG which is 320 vs 128 the difference is significant.

Thanks, RPM.
I signed up with MOG (the free one) just to give it a try. Indeed I can hear a difference in sound quality over Pandora.
