Upsampling

Same purpose as all other tech specs, to get you thinking they matter. The more thinking the less listening. Ad copy is a lot easier to write than it is to make sound quality you can hear.

Two fold.  One, the filter behavior improves, hopefully pushing any aberrations out of the audible spectrum. Second, the DAC chip itself may perform better with more data, even if that data doesn't actuall increase the content of information from the original.

Upsampling is not all the same however, there's linear extrapolation and curve fitting with the latter requiring quite a bit more math and compute horsepower to do right.

In the end, only your ears matter though. :)

right on the money Erik. I stream at DSD 512. To my ears it creates an airer more detailed presentation that I like. Not all gear can do this successfully.

Hey @tuberist,

I tried this with my Brooklyn. I did not like it at all, especially compared with original DSD files from Blue Coast.

YMMV,

Erik
