Squeezebox Touch: jitter thru wi-fi?


I'm looking into a SB Touch to go with a non-dedicated PC, and to feed my preamp (so initially, I'll use the Touch's DAC).

Eventually I plan to buy an external DAC, and I'm interested in the asynch USB DACs, which are supposed to avoid jitter through that interface. There's a Touch tweak going around to turn the USB input into an output, so that would be a preferred way to connect to said DAC.

Now how about mistimmings in the data transfer (jitter) through my wi-fi from PC to Touch? Is that an issue?

Thanks!

Direct Async USB and Firewire are generally the preferred connections, although there are some new network players too.

For a hi resolution system, I would avoid wireless. For streaming background music and such, it is great.
No.

Jitter only comes into play during the analog to digital conversion process which occurs all within the squeezebox using the internal DAC or between squeezebox and external DAC if external dac is used.

The only issue wit Wifi comes if teh bandwidth is not sufficient to provide data to the Squeezebox fast enough to convert in real time. The result is temporary delays in the playback until the Squeezebox receives enough data to proceed converting to sound in real time.

Wifi bandwidth is affected by noise/interference on specific channels, physical obstacles in the path of teh transmission between remote devices and router, and physical distance between router and remote devices.
Mapman - I noticed a few second delay with my Airport Express. I think they fill the buffer to prevent drop-outs in case of interference. Jitter-wise AE was tested by Stereophile and measured word jitter on digital output was respectable 250ps.
Kijanki, yes, buffering helps reduce dropouts however I believe if throughput between server and Squeezebox client goes too low, the buffer still might not be filled fast enough to keep music flowing. That is what I experience on occasion with similar Roku Soundbridge product, and would expect similar with any network player device.
Mapman, I have dropouts sometimes (once a week) - much better now since I found microwave oven frequency in its manual and changed wireless channel away from it. Ideal would be to switch to 802.11n (5GHz) but my MacMini doesn't support it.
