Wifi vs USB


I've been following lots of reviews on USB DAC's but missing a crucial piece of information:

Is streaming wirelessly to a DAC more or less as good sonically as going with a good reclocked USB DAC directly connected to the USB port of a computer?

What I really want to know is: for my main audio system, do I need to keep the computer with the music database wired to the system or can I get equivalently close audiophile sound by streaming the bits wirelessly to the DAC?

If the latter (I hope!), then what is an example of an acceptable configuration?

Thanks,

Roku or Squeezebox for a PC, Apple Extreme for the Apple world.

Squeezebox is rumored to have a better built in DAC for better sound out of the box and costs more. Roku costs less. I use external DACs with Roku for best sound. Many do with Squeezebox also.

Also Logitech seems more active in releasing new versions of Squuezebox these days whereas Roku Soundbridge design has been more static. Newer higher bandwidth wireless N support might be useful if Logitech provides that yet and your Wifi router supports it, but Wireless G works fine as well and costs less.
Art,

I did upgrade to a top of the line Netgear wireless N router recently from a secod or third generation Linksys that I had been running for years. I found this has helped with throughput to my Rokus, which are only wireless G, despite technically the same maximum wireless bandwidth, in that the range appears to be greater and I believe the processors and software used are faster and more efficient.

We tend to forget sometimes that devices like routers are just specialized computers with specialized processing, software etc. This kind of processing generally gets better and faster over time, and not all modern routers are created equal. A faster more efficient router still helps even if the pipeline from router to wireless devices still has essentially the same capacity (wireless G protocol) as before.
