So, does apt-X sound any better? Does anyone have any objective or subjective data regarding this?

The thing is, I bought some headphones that are only compatible with SBC and apt-X (creative's). The headphones have way better bass response than my other only pair of headphones (in-ear...), but there's some weirdness in the sound and I ponder whether that's how artifacts of SBC sound, or it's just my imagination. I also ponder whether apt-x is really any better considering it has the same bandwidth limitations as SBC and is an ADPCM codec.

If it is the case I might actually look into this... (given enough time, of course ... )
