Can someone tell me how I get started? Very interested in this as a source, but like many others, I have no clue how to get started. I know that I am not the only one. I just don't have the time to do research, so if the folks here can just make it super simple for me. What do I need to buy? How does this plug into my DAC? What do I need to download? What OS? What programs? What players? How do I use it? What about mouse, keyboards, videos?
