Airport express does sound good Lenny_pt and especially for the price. What can make it sound better is something like the Pace Car in mode 3 with the Airport Express modded and slaved to it. But the Pace Car and the modding process is expensive unfortunately.

Blindjim, it would be nice if you were right, that a DAC can eliminate jitter. I haven't found one that is not affected by changes in jitter performance. I also don't see improving jitter performance as just changing flavour. I have generally found that improved jitter performance improves everything - smoother, tighter, more resolution, less glare, better dynamics.

Check the 'corrected' jitter figures JA made in his review of the Bel Canto e one DAC3 in Stereophile. Additionally, the balance of the tested specs of the BC D3 also in that same review.

The important part of it all is just how much jitter, or how little jitter, can a human being actually hear?

At some point one has to be reasonable with specs. I've yet to find specs which dictate how a thing will sound, regardless how good or poorly the device measures out at. Especially given one uses only the manufacturers specs.

The only specs that still carry weight with me, are price, size & weight, (sometimes), and color (sometimes).

It always comes down to hearing it. That's the spec to go by.
