Head-Fi: Covering Headphones, Earphones and Portable Audio

	The headphones show is over If only a round-trip shinkansen from shikoku to tokyo didn't cost as much as much as a nice headphone amp...From the photos, it looked great. Looked more like an amusement park than a show! Hope you enjoyed yourself~

	The headphones show is over Hi Sasaki, Thank you for the links. Once again, the event was very bad timing for me. Hopefully I can make it one of these times. Did you get any more information about the new Fostex headphones? I really like my D7000s and am hoping those will be great. Yoroshiku!

	Don't limit yourselves! I love John Coltrane's Blue Train and Hank Mobley's Soul Station. The music is just stellar!

	SR71A has just landed! I like the UE-11 with the XP-7 even more, although I can live happily with the SR-71A.

My Audio Fingerprint...

Tone was perfectly fine...

I just didn't have access to even an adequate cameraphone at the time of posting this, so I thank you for the interest, (seriously, THANK you! :-) ) and it gives me a little photo project goal for Head-Fi...

Oh and you all may also be interested in my audio stuff at: Any Manner Of Things…

and for pretty or pretty weird pictures my photo blog at:

	My Audio Fingerprint... I'll take that as a REQUEST for pics... ...and will create and post them once I get moved into my new place and get internet set back up. !!! Thanks for the interest ;-}

What is jitter and what does it mean?

agreed with most above i am. id like to add alittle info to hopefully take the mystery out of waveform ringing. A digital signal entering a chip (like a DAC) will only cause audible "jitter" if the following conditions are met:

the DAC's power supply isnt "weak" under full output (ie. well regulated to within 100mV or less - usually within 25-50mV of the target Vout).
the input ringing does not cause a logic change, (ie. excessive ring amplitude to cause an input to swing low/high enough to be considered a logic low or a logic high when it is not desired).
the specified input frequency/voltage is not exceeded on either the DAC or the traces leading to/from the DAC, which would cause excess ringing and possible old data to still exist on the traces & IC pins. Traces on any circuit board will have some amount of inductance & capacitance as does the thousands of transistors within the DAC IC itself.

So audible "jitter" is most likely some kind of "hickup" in the bits that make a frame of audio in your audio file.
