I acknowledge that if I search for this topic I will eventually find info, but I got tired.
1) I ultimately want digital out from my PC (via usb, coax, or fibre) to go to my integrated DAC which will accept any of the aforementioned connectors. I want the signal to be purely digital and unadultered along the way.
2) What software is typically recommended for this? How do I ensure that there is no loss from PC to AMP (well, DAC)?
3) Will iphone to USB port in the DAC be pure digital transmission, or the iphone put out an analogue only signal?
4) What software will allow (easy) playing of FLAC sound?
These are probably well-posed problems with easy solutions, but I'm too dumb and grumpy for the moment. My search will continue. In the mean time, I appreciate your help.
I think my amp is a NAD 375BEE with the DAC integrated.
...For fun, but not really relevant, my speakers are Sonus Fabers. I have a Roland V-Piano in the system as well..
