Music files are on a hard disk in a computer, USB drive or NAS drive
Music files were created with a quality software ( in my case Exact Audio Copy @ 16/44 )
Using Audirvana Player software ( others could be inserted here also ) on PC or Mac
Step 1 Audirvana sees the music file and reads the digital file
Step 2 Audirvana software converts/upscales the digital file to DSD 256
Step 3 Audirvana sees my USB DAC and sends the digital stream to the DAC
Step 4 The DAC senses the digital DSD stream and converts that digital stream into an analog signal
Step 5 the DAC then sends the analog signal out via XLR or RCA depending on DAC capability
Step 6 The XLR or RCA is connected to a PreAmp or directly to and amp which amplifies the analog signal to the speakers and we here music.
I think that is the process Please correct if wrong
1 the conversion of the 16/44 digital stream is processor intensive ( my belief ) therefore where the process occurs is important and why having that process done on a computer has advantages ??
2 There is much talked about a computers being ( Electronically Noisy ) and therefore adds noise to the digital stream during processing which is then sent to the DAC , while I am sure that is measurable is it significant. Also just because you have that process done in a different ( all in one streaming box )why would the process be less noisy ??
