It has everything to do with it. Your telling people an off the shelf switch fed with cat 8 terminated on premise (I assume) is just as good as a EtherREGEN with say and AQ cinnamon cable. I believe that is hogwash. So I say your leaving performance on the table. You then imply I have no knowledge of how to make it better. Well I do, as do others who have explained all the small parts and pieces that make up a significantly better whole. Your digital system, especially the steaming portion is not optimized. An optimized steaming system will come close to the performance of stored on rhe hard drive playback. On the hard drive will beat it. But it gets good enough that you stop worrying about where the media came from. Hard drive, NAS or internet. It all sounds darn good. Yes it cost more money. Maybe $2k to $3k to do an entry to mid level package correct. After that you could spend another $3k, but that is going to bring a smaller gain than the first outlay. And for how much money people are spending on DAC and servers. Many ponying up $20k to $30k or more, its foolish to not invest the $3k to set the digital backbone right.
