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!

TCP/IP cannot guarantee that data arrives "on time", so it doesn't matter whether one is using wi-fi or ethernet, it still has to be buffered and reclocked.

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.
