OK, I wasn’t sure where to put this, but since it’s related to my DirectStream use - I’ll put it here.
So I’m following the adventures of a friend who’s doing the budget version of Paul’s Mac Mini upgrade, and I’ve already done my upgrades to my Tiny Form Factor Lenovo PC (SSD drive, Linear PSU, shielding, software tweaks, etc). As we fine tune our source devices for digital media, I sometimes get flustered and go to Ted with a “why does this make a difference!?” question. Oftentimes, his answer boils down to many speculations and not much more…I’m unsure if this is a lack of time or patience with me (and I totally understand! LOL), trade secrets, or he really just doesn’t know because of so many variables…but the one thing these changes and Ted’s responses have in common, is noise transferred from source to DAC.
So I’ll get to the crux of my question - why haven’t we (by we I mean PS Audio or high end audio in general) moved to some sort of Gigabit Glass Fiber connection between our digital gear? Why aren’t we isolating the sources of noise between the gear with fiber? Or hell, is there a way to use fiber between sections of the DAC itself even?
Am I looking at this wrong? Is the “noise” we’re eliminating by tweaking our computers not carried by the copper, but in fact something happening to the transmission of the bits? I guess that’s one of the questions I didn’t feel really got answered in my many “why is this” to Ted. I’ve read articles that mention the leading edge of the bit causing problems, or the leading edge having some sort of an echo slightly +/- the original bit. But I’m no EE by any stretch, I’m just a smart guy who’s really good with concepts trying to wrap my head around all this, and maybe improve the state of the state while I’m at it.
As always, sorry so wordy, and I hope it makes sense what I’m getting at.
