Where do cables upgrades have the most impact?

@teo_audio  I realize this goes against the grain of what you posted : )  however, do you have specific advice on how to move along the 'journey' more efficiently?

Why does a manufacturer make and sell multi-thousand dollar amps with exotic power supplies but with power cables that are sub par. I just have a hard time getting past that idea.

Ponder why component manufacturers showcase their products in partnership with any number of aftermarket cable companies?

BTW, you are way past the proverbial 'newbie' status. : )

@teo_audio  

To try to at least build or modify a single piece of gear. Or that built piece of gear, being modified at least once. In some way. To get an understanding of the complexity of the signal in the boxes. This might be a way.

Point noted. I will move in that direction, holistically.

Both of your posts have been helpful. Thank you!

@almarg  Thanks for your post. All of your 'factors' are important in one's consideration, as I myself recently learned, via you. : )
