Hopefully I'm not reposting a previous question, but i did search quite a bit.
It is my understanding that pcm audio coming from the optical audio output of my computer is never processed through a DAC until it hits the receiver. Am I correct in this assumption?
I currently enjoy most of my music collection and all movies via this method.
Movie audio encoded in their respective formats are recognised by the receiver (dts/dd).
Playing mp3/flac formats results in a pcm logo on the receiver to be decoded by the DAC there and I assume it is not being converted to analog in the computer audio hardware just to be encoded as a pcm stream before output. This would seem redundant and affect quality. The reason I ask is there are a few threads regarding a seperate unit (external DAC) via usb to convert digital audio to optical signal or analog signal.
So I guess I am wondering if there would be a benefit to an external decoder to convert first (once) to analog and input to the receiver that way or if the optical output on my pc to the optical input on the receiver is achieving the exact same signal flow.
Also, is it better to have the computer output 24bit 192khz signal hoping that it is oversampling or leave the output at the native mp3/ bitrate of 16bit /44khz and have the receiver do oversampling. (does the receiver do oversampling of pcm signal?)
The setup sounds quite fantastic the way I use it, but if I am missing something, it is always nice to upgrade
