Mike - as Jock quoted my original post to this question, I feel it is important to expand on it. First of all, chasing the next greatest DAC is akin to chasing your tail. The DAC is only PART of the entire equation. You cannot and should not separate the processing side from the entire equation. We hear all this talk about jitter (which is timing) and controlling jitter coming into a DAC. As Paul McGowan pointed out in a recent blog post, it is possible for most people to hear jitter at only 2 picoseconds. That's insane! It's no wonder all these network music players/streamers (Naim, Linn, Lumin, etc.) sound better than any stand alone DAC I have heard. Trusting timing and overall sonics to a PC with God knows what sound card, what program, what OS, what USB cable, etc. is silly when you stop to think about it. But when you're in the DAC zombie mode, you can't see the forest for the trees (or at least I couldn't).
Buying a DAC is like buying the front half of a BMW and then trying to make it work with the back end of a Mercedes Benz. I was caught up in the hottest DAC of the month pursuit. That never ending pursuit for digital bliss. But like the dog chasing his tail, it makes no sense.
Mark and Jock both kept telling me get a network music player/streamer. But I thought, "how could they be right when everyone is chasing the latest DAC?" What's the definition of insanity?
Network players aren't for everyone. If you can't be bothered ripping your CD collection, then stick with a spinner. If you like working with Windows or Mac in your listening room and you like the pursuit for finding the most revealing, highest resolution (sonically speaking) DAC, then stick with the Mc & DAC combo. But if you want to hear full bodied, analog sound, without any digital edge or harshness, then get a streamer. There are plenty of reviews out there about the Lumin and other streamers, not to mention my own.
Last but not least, the implementation of the Wolfson DAC chipset driven by a modified version of Linux, in a solid aluminum case and a completely separate power supply produces the best digital I have heard to date at a price that makes even thinking about a $30,000 DAC + USB + Windows/Mac + JRiver/Audirvana ridiculous.
