With "normal" audio gear we all knew every detail about music on its signal path at what we needed or wanted to do to increase fidelity.We knew the weak points, what impact various things had on sound etc. from the record->needle->power->wire->vibration->direct drive/belt drive->etc. etc. or with CD->transport->DAC->wire->power-> etc.
Now with computers we use "drivers", RAM memory, ASIO, etc. all before it even leaves the box.
What real aspects of the path can and should be looked into. There is a huge GREY area that I am not so clear on....Right off the bat I would imagine that there is an enormous amount of jitter in computer audio due to the very "electrically" noisy power supply and circuit boards etc.
My assumption is data [music] stored on a HD is goes through a series of drivers [ASIO] etc. when called on to play, after that it is buffered on RAM and is streamed out of what ever port it is commanded too straight from RAM...if its digital it will go out from RAM as a pure digital signal out s/pdif bypassing all the curcuits of a sound card or on board sound device.
If it is commanded to go out as analog it will be directed into the curcuits of your sound card etc. for D/A conversion and then go out.
Is this assumption wrong, please someone add details or correct me.
My feeling is that if your going digital out to an external DAC, your sound cards only need is for the port to provide a path for the signal and nothing else.
