Best digital stream player


No matter how expensive any cd player is, it is just do a best guess of what is on the cd. I don't think cd player will be completely gone in a couple years because LP is coming back. But I feel the digital stream player have big advantage over cd player and all audio company will come up with their new digital stream player in the coming years. Digital stream player either use usb or network cable to directly read music file from PC/file server and are slowly adapted by audiophiles.

Digital stream player is still new to lots of people. Which one is the best digital stream player in the market?

1)DCS Scarlatti upsampler
2)PlayBack Designs MPS-5
3)Linn Klimax DS

Or is there any other newcomers better than those three?

Do any of these sound better than an Olive or a Mac coupled with a good DAC? More expensive certainly, but better sound-wise? Just asking, I'm not being rhetorical here.
On a realted note, is it possible for any traditional transport to be as good as something like the Olive HD feeding a high quality DAC?
Recommend you audition the Naim HDX. It is hands down the closest thing to a good quality vinyl front end I have ever heard.
Aside from the DAC implementation, what are these products doing to the digital stream that could impart their own sonic signature? When you install Windows, does the code change depending on if you're using an Asus DVD-ROM or a Toshiba one?
