What do you want to hear when you listen to music? Do you want a lower-fidelity version of what the artists, engineers, and producers heard in the studio? Or would you prefer to hear exactly what they heard in the studio?
Of course, you'd prefer the latter. But you're probably getting the former - unless, that is, you're listening to high-resolution downloads from HDtracks. If you're listening to CDs, MP3s, or even vinyl records, what you're hearing is not a precise copy of the original digital recording or analog tape. It's downconverted. If it's on CD, the digital resolution has been reduced. If it's on vinyl, the audio has been remastered and the record you're listening to is actually a third-generation mechanical copy.
Sure, it might sound ok. But it's not the best fidelity you can get. HDtracks is. And HDtracks and Sound+Vision have put together an introductory sampler to show you just how good high-resolution listening can be.
