Summary: Not being a technophile I was intimidated by the thought of a network device. Rest assured the NA7004 is virtually plug and play. I plugged it in and five minutes later music was playing through my speakers. My needs are for detailed classical listening. So quality of sound was my main goal. Paired with a Marantz PM8004 this unit has meet my needs. Installation was quick and easy. Now the sound. After a fair amount of break in time I would say that the sound is great.
