Just to add to what others have said, streamers/digital sources all sound different. I am on my third streamer, the other two are okay, this one is better, all through the same DAC. I will keep looking. I have one of those Nakamichi 5 CD changers and put it in my main rig once. It has no digital out, so you get the digital source and DAC in one. Almost unlistenable compared to streamed versions of of the same ripped CD's through a streamer. Anything you do will be an upgrade there. I have gone completely digital with all my CD's ripped on a NAS, no plans to go back to a CD player, however I understand why some folks like/want them. But understand, even if you are using an external DAC, the digital stream coming out of the CD player can affect the sound like any streamer can. Everything matters if you have the ears to hear it.
The Ygg is a good choice, I have a Gumby and am very happy with it.
