'But let's say that in the privacy of my own home that I feel the urge to make a marked difference, what sort of arcane ritual would it entail?'

You need to learn Intel speak and have patience. I don't actually think that changing USB polling is a solution, or lead to that much improvement.

Disabling USB ports is, to me, a ridiculous solution just because the usb audio makers have hijacked a connection meant for other things.

"Disabling USB ports is, to me, a ridiculous solution just because the usb audio makers have hijacked a connection meant for other things."

Yea, I know what you mean. On the other hand using a GP computer to play music seems like the epitome of that to me and yet I find both the concept and results pleasing. The amazing thing is that it can do it at all let alone so well.

I'm comfortable with making adjustments and selecting player software to achieve good sound with internal audio and it usually causes little or no impairment to 'normal' usage so I hope for something along the same line from tweaking the USB system.

  may be up to 12 usb ports on a general use PC. Do you want to disable 11 and change polling for the lot?
  
  And, do you want to remember enabling them for use when you want to?

    "Do you want to disable 11 and change polling for the lot?"
    
    Beats me, it's all TBD.
    
    Isn't this in the same vein of not listening to expensive hardware because you might decide you like it but really don't want to shell out the money?
    
    I think the first step is finding out what sort of differences things make then one can decide their value vs what they cost in dollars, time or hassle. Right now I'm just kicking the tires out of curiosity, maybe I'll learn something...

      Try it, it's a hassle.
      Changing the Polling frequency just changes the way the signals intermodulate. Will that be an improvement for every system? Not likely.
      It can also make your usb devices less responsive.

        And your evidence for the "just" bit is?
        
        I ask because the link suggests that, despite being confused about what was involved (you muddled it with the very different gamers' trick of increasing HID polling rates), you supported the suggestion.
        
        Note that the RegEdit change discussed lowers the rate at which USB ports are polled from 1KHz to 200Hz and is applied per controller. I see I suggested that:
        . . . the default MS polling interval is one millisecond, i.e. its frequency is 1 KHz, bang in the middle of the mid-range. If the activity, esp with consumer-level DACs, exacerbates jitter even slightly, the effect of moving it to the less-sensitive 200 Hz region might well improve the sound.
        It can also make your usb devices less responsive.
        
        Sure. Drives take forever to copy, scanning slows to a crawl, the sky goes dark, cows starting herding beneath trees and there's an eerie silence.
        
        Solution? Don't perform the change on controllers driving HDDs, scanners - or cows.
        
        But I'd wager that neither you nor anyone else has ever spotted a performance difference. And were Rick do so, he might just have the gumption to reverse the change.
        
        You're making this up as you go along.

        do you know how intermodulation works, whether at 200 Hz or 1 KHz.
        
        It's better to keep quiet if things are beyond you.

        That's true - but neither did anyone else.

        Good Advice.
