The controversy over streaming vs. physical disc seems endless.
On the one hand, we know that all things being equal, there’s no difference to the DAC how it gets its digital audio data. It can come from as close as three feet away via cable or can stream from thousands of miles away via the internet. As long as the bits received are identical it won’t matter.
Yet that seems not to be the case.
Discs currently outperform streaming on any platform I’ve experimented with by a lot. I believe that has nothing to do with the bits and everything to do with how they are received and processed (though this does not explain in any way why Tidal and Qobuz sound vastly different with Qobuz the clear winner—a subject for another day)
Let me share a bit of my thinking. If I upload to Dropbox an Octave master DSD file, then download it and capture it to a USB memory stick, and play that stick in our PerfectWave SACD transport, it sounds absolutely identical to the same file as played on a DVD data disc. Thus, the round trip travel to the Cloud and back again have zero impact on the data. Transferring that same data from a hard drive on a Qobuz or Tidal server should then be identical to that of a Dropbox server. In fact, several of these choices employ the same Amazon Web Services for their server. For all we know, the two could be housed in the same building.
Yet, they sound remarkably different.
Tomorrow I will discuss why I believe that to be true.
