I have a Marantz CD6004 and find it ok. I have lots of riped material but the 6004 cannot be used as a DAC. Is it better to get another cdp or sadc that can be used as both player and dac or use the current unit (marantz cd6004) and buy a dedicated DAC. What is the price point to get equal or better quality sound equal or better than my current cdp? Please give your feedback freely. I will be glad to hear all critics before deciding on a budget.I am prepared to invest another couple of hundreds at most.
