Hi everyone. I’m new to Hi-Fi systems and have recently built my first system (Marantz PM6006 Amp/Q Acoustics 3050 speakers). Really enjoy the sound, but some of my audio sources are pretty questionable and inconsistent from my PC, so I would like to buy a CD player for it for a more stable quality. I was looking at the Marantz CD6006. My question is this: If I already have the separate Amp, do I need to buy the CD6006? What do I gain from buying that, does it act as a pre-amp? Or is a cheaper CD player that isn’t as big as the CD6006 going to cut it. I’m not entirely sure what it does, other then to send the CD source to the Amp. Also, what cable connection is best? Currently I’m using optical cable to connect my PC to the Amp. Sorry if this is a softball question, I’m new to audio equipment and want to get better acquainted with it. Any help appreciated, thanks!
