Where is the weakest link?


So whats the priority in fixing the path between the ugly utility pole and the speaker connection point? Dont say all the above.  My system is revealing so i need to give this area serious attention.

between amp and speaker,
processor and amp,
dac and processor,
dac and streamer,
router and streamer
Etc

i have thick interconnects, some better than others, but not the cheap stuff, have spent alot on cables to speakers, including center.

ethernet segment dont excite me due to self correcting process that oversees packet delivery.

i dont use balanced and probably should.

List your equipment and we'll tell you the weak link but be prepared, it might not be the path you are thinking about. 
"...Its a general question relating to cabling..."

I can't help you or your system if I don't know what it is. Generalizations usually don't work out...that might be a generalization but mine works.  
It depends. It is an unsolvable problem without knowing the components. I have addressed mine starting with digital interconnects, analog interconnects, speaker cables, dedicated line, power cords. But you have to have components of sufficient sensitivity, appropriately matched, before really knowing what to go after first.

.

There is also the issue of how clean is your power and how much reactive stuff you have in your house.

Your system is a system. 
Heres system,

signal begins with a nucleus connected via usb carbon from audioquest to a chord tt2 dac, which connects via monster rca cable to a NAD M17 v2i processor, which connects to a mcintosh mc 255 via rca cable (sb balanced ?)..  

Am considering transparent super cables to connect to b&w 802 d3 mains and b&w htm2 d3 center.   

very appreciated, thanks
