Unless your DAC is not high quality, i suggest using your digital-out from your CD player to either a separate high-quality DAC or to the DAC module in your Integrated amp, if you prefer that. The decision to rip all or part of your CD collection to lossless files on a computer or network server should be a separate question. Having your collection available on selection from your PC or MAC is very convenient.
Try to avoid duplicate DA Conversion with USB drive to Amplifier direct
After my recent acquisition of an Arcam SA20 integrated amplifier and a pair of Sonus Faber speakers, the next logical step appeared to be getting a new CD player with a respectable DA converter, as I have a large collection of musical CDs. However, the Arcam SA20 has a USB port and a decent DA converter already. I am wondering if I should just rip my CD collection to a USB flash drive and just plug in to my Arcam SA20. This supposedly avoids getting a duplicate DA converter (in an extra CD player); any suggestions or thoughts?
