Relative Importance of Analog Components

@needfreestuff 

that's why the question was in the scope of upgrade, which one would be the best improvement

@dogberry Stated "or where to direct their attention if everything seems to be working fairly well."

@needfreestuff in a very "non-prolix" response has summarised very much of what has been said in earlier posts.

To get to the optimal, all Interfaces are requiring attention.

It is the how much attention that is given, that separates the assembly as being Only Capable or Bordering on Optimised and Quite Capable.

For creating the Interface between a Assembly of Parts it is not strange or uncommon, to see where quite experienced individuals, that are sure in their knowing limitations in knowledge are present, and are willing to call on the Services of Skilled Technicians who set up the Analogue Front End or Invest In/ Hire a Computer Software Program to assist with the task of Setting Up.

Set Up Services or Software and those that are with acquired skills from a time served experience, do not focus on one part only within the assembly, the marriage of all parts is the focus .   

I am seriously freaking out, has he always been like this? Does he have children in the basement?

😁 We're all different and I'm pretty tolerant of neurodiversity, which tends to come into play on audio forums. But even I, broad-minded as I am, don't want to look in the basements belonging to any of you. I don't even like looking in my own.

at least I don't have a basement - living on top of a rock :)
