Any signal that is added to a sinewave ( e.g. matrixed or superimposed) is a form of distortion of the sinewave.
People often imagine that digital transmission works like a kind of morse code. In practice it is usually a continuous waveform having specific attributes which as they occur are interpreted by a detection circuit as representing a change in value ( + or -, 0 or 1, on or off). Digital engineering works by analogue means :-)
Do you have any links to some good information to learn more about this. I am trying to read up on it.
I'm using a TPLink to my Marantz NA7004 network streamer. Should I use something else???
IF you can't hear a difference.. then Is it relevant?
Ideal is exactly that.
Real life is somewhat different.
The link attached leads to quite a good and simple Wikipedia article.
In respect of your other query I don't know exactly what you are doing and what it is that you link digitally to your streamer, what connections you use etc. Looking at the specifications I would guess that the usual connectivity would be via USB or ethernet but I see that SP/Dif co-ax and optical inputs also feature. Do you connect to a NAS or something similar?
If you are using TPlink for other types of digital distribution via the home mains wiring then the damage is done and plugging the network streamer into any wall socket will still mean using distorted power. However if the TPLink connection is only for this device then I would switch to a hard wired connection suitable to your needs and the device's connections. So ethernet cable is one way to go but I do know of people who say that using computer network optical cabling is better. However this adds a level of complexity and expense. Sticking with basic but decent quality Cat5 cabling if suitable you could then just try a connection with it against the TPLink and see what difference it makes - that would be a cheap comparison.
In any case I am sure that there will be better qualified inmates than myself able to deal with this.
In my last house I did "hard wire" it with cat5. This house that I recently moved into, there is NO way I can get a cable from the router to the streaming device. So it has to be wireless.
The TPlink is used only for the streamer.
One odd thing about the NA7004. I tried patching the digital out from my NAD (Ok stop laughing) to the digtital coax in. Every connection with exception of my ipod I get "unable to unlock signal" error messages.
OK, no wires.
I am way outside of my comfort zone with this recommendation but if I understand the device it will connect to your router by wifi and to your network streamer's ethernet connector. At least that is how I see it.
Not sure about the other connectivity problems. At face value the Marantz can cope with a number of different types of digital input.
