I did the upgrade and the sound still sucks. I'd like to go back to how it was before doing two upgrades that made things worse not better.......
You know, come to think about it, the volume of my music did seem lower. Granted that I do wear earplugs but it did seem a bit lower. This is from a cabled mp3 player.
I'm thinking of introducing a 100w linear amp... That should help the volume a little.
