I was, in fact, very leery/iffy about this as well at first....
It has changed the overall clarity (using Altec buds btw) and bass management. I was impressed and forgot about Dre. lol
As far as an EQ, I'm using the recommended AudioFX app/widget to adjust.
PPL have to remember though, the quality can only go so far as the download--i.e. bit-rate, source, etc. I always preview my songs before a full download.
I don't believe a change in ROMS would affect this audio flash--it should be set in stone unless you recover to a ROM before this MOD still using DSP..
Correct me if I'm wrong on this.
*Someone made up another thread basically on this AGAIN----
But this is what I posted in the "Music lovers" thread.
