Oh, just read about it. It's redundant in the system I'm doing. The Melco takes care of the clean signal. It's a direct ethernet connection to the Ayre QX5 Twenty. I'll be using the streaming device in the Ayre and not using the one in the Melco. It seems easier to just control the noise at the source using the optical converter and simple ethernet hook ups. Let properly designed pieces like the Melco and Ayre take care of the rest as they too isolate and clean up the signal before sending it forward. If you don't have streaming in your DAC, like the Ayre does, then you would possibly need a bridge I assume, to run your internet music. That seems like a waste of money when using the new DAC's that are digital hubs I think.... I may be dead wrong here. If you think I am, please let me know what I"m missing as I"m trying like heck to get a total handle on all of this. I'm lucky to be getting great advice from a couple of audio engineers that I trust and who run digital audiophile boards etc... or are main posters to help others. So many cool products out there that it's hard to always figure out what we do and don't need and what works best together as just like in analog products, the best isn't always best with the rest of the system. Just need to be informed and match properly. Thanks for sharing and keeping this thread going in a positive direction. Learning a ton.
