Ok so I tried flashing it on RC 5.6.1 and found out the following:
1) The 'shhhhh' sound is present only on the phone speaker.(Clocked at 604Mhz)
2) Using a headset, I did find a difference in the quality of the music. Now, I'm not an audiophile so I won't be able to tell the minute differences and it could be a placebo but it did feel good.
