Firmware update 1.3.0.x

I absolutely disagree with you. I hear no sound quality change on mine, just a change in the volume control law which I am sure anybody can get used to after a while.
I have had kit in the past with much less logical volume control actions than either the original or current volume control laws used by the Phantom, usually in the name of sound quality improvement of a non-logarithmic pot.

I don't look at the number, personally, I just adjust the volume to sound as loud as I want and since nothing has changed on my Phantoms apart from the number displayed in Spark when I listen it makes no difference at all.

I agree, "louder" and "more bass" doesn't make much of a difference when there's an abundance of both. To my ears the Phantom sounds better than ever and Spark has improved, no more skipping tracks on the playlist.
