Sorry. Just found it. Somehow it seems like because both weren't liked I didn't notice it existed.
You may close this now, makes no sense staying open.
mp3 at 128Kb/s is a bit too low.
For the speakers I use reducing to 96Kb/s also works well. I use no high-tech or expensive speakers and I need space. So 96 Kb/s vs 128 Kb/s makes no noticeable difference (in those speakers) (only less than 96Kb/s starts to make good difference).
