Wow, this has really gone off the rails.
High quality streamers pretty much take the network out of the picture. A great streamer simply requires a trickle of bits and will cashe them and isolate you from your network. You can improve the performance of a mediocre streamer by improving your network. But, this is the hard way.
Go check out an Aurrender streamer… one that is equal / compatible with the rest of your components and the network becomes invisible… unless there is something truly wrong with your network… like it throttles to 2K throughput.
There are other great streamers. But screwing around with your network unless that is a labor of love is waste of time.
My streamers provide sound quality equal to my great vinyl system through wall wart wifi extenders.
