Anybody want a laugh?

I stream all my music from either services or ripped files. I have a basic Netgear modem and router. I network a NUC running roon in my office to a raspberry pi4 running Ropiee with RAAT roon's transport protocol on my network. I then connect the pi4 to my integrated amp with the USB cable that came with it, the cheap black one. I use basic canare 4s11 speaker wire. I have wall warts connected to my panamax surge protector on different banks with my integrated.  This is plugged into a basic industrial grade receptacle on a regular 15 amp circuit. Pretty much everything you're advised not to do. Yet I have a noise floor so low I never hear any, the quiet parts of a song are dead black quiet, no harsh female vocals.no hum or hiss.  Excellent timbre and separation of instruments. At least as good as my speakers allow. How is this possible? 

@djones - well it’s a good thing that well healed audiophiles all know the fact - "measurements mean absolutely nothing", right?

Well I’m into computer audio, and I’ve been following the advice of the "people" in the forums with excellent results - just saying.

And as it’s known snake oil right here in Agon, then we should just let these poor unsuspecting people enjoy the music and you’ll stick to what you already have.

The noise floor cannot be heard by itself.... Only when we modify the electrcal grid and then perceive new details .... Perceiving directly the noise floor level is most of the times not direct perception except in degraded case of a very high level....

@djones - maybe because it's superior and you have just validated my comments? And do you suppose that it cannot possibly be improved upon, in any way by anybody?

i begins to hears in an indirect way the noise floor of my audio system when i begins to controls the electrical grid of my house and the noise floor of my audio system.... Not before.... :)


A hum or a hiss are only particular noise not giving direct experience of what is the noise floor of the house where is embed the noise floor of the audio system....

Harsh female vocals are explained more by defects in the audio system than by the noise floor level of the house or of the audio system by themselves....
