Headphone jacks are, for the most part, pretty good. However, I have never come across an MP3 player or portable cd player whose onboard circuitry is as good at amplification without distortion as a halfway decent stereo system. I've owned and used my fair share of high end cans and the amplification circuitry is of utmost importance to get the most out of them. If you're dropping that kind of coin on headphones you should probably be running a separate headphone amp anyways.wco81 wrote:Hmm I'll have to see if there are reviews which measure the differences between line out and headphone jack. Like I said, maybe more noise so that would show up in S/N. But frequency response should be similar.
If headphone jacks are so bad, there would be no market for expensive earphones like the Bose QC, the expensive Shure and Ultimate Ears, etc.
BTW, good detailed review of the Zune on Engadget.
Its good to see the Zune getting a somewhat decent writeup. I think a lot of people are judging it because of how it doesn't do certain things but aren't fairly talking about what it actually does.
