Are you suggesting Amazon is using DSP to get high resolution files? This would be quite a story.

 

I think he means re-sampling, kind of like what HD tracks sometimes does (or at least sells).

The "new" Beatles album, Abbey Road, sounds pretty good, even on Amazon.

I don't know where along the chain the up-sampling takes place.

 

(I also have wondered if Amazon (via their player), or whomever provides them the files, is somehow enhancing the bass. It sounds significantly more pronounced/boomy in my system.)

[wgscott]

I think it would be worth measuring, if for no other reason, than to do a santity-check.

 

Subjectively, it sounds different/more bassy.  Even if this turns out to be true, there is the question of whether it is an artifact of my (or other user's) playback chain, software, etc.

 

I'm not sure how you could tell whether the file is being delivered to the DAC bit-perfectly, but if it is possible, that should put all concerns to rest (unless Amazon uses a noisy power supply on their servers).
