Internet Cable speeds & Power Line Speed Options


My Internet cable speed is 10Mbps. What impact, if any, would increasing it to 50Mbps (cable speed) have on the sound quality of listening to streaming radio stations from the Internet?

I am using the ASUS homeplug av powerline adapter kit pl-x32m rated at to 200Mbps (Ethernet over power). They offer a ASUS PL-X51P/PL-X52P 500 Mbps 4 Gigabit ports powerline adapter kit rated at 500Mbps. What impact, if any, would increasing it to 500Mbps have on the sound quality of streaming radio stations from the Internet?

In other words, would any of the above external speed increases (cable and/or Power line), improve the sound quality when streaming Internet radio stations?
