What makes the biggest difference in sound quality?

Relative humidity and elevation.

UNBELIEVABLE!!! WHO was the IDIOT who doesn't even know WTF a fish is?!? It's a "VEGETABLE".....MORON!!!  (;

😂😂😂😂. So….is fish considered meat or not? Answer the rucking question good dammmit!

hi ted, may I confirm by your most recent post that your own order would generally begin with power cords? how would you rate the others after that, in this case, or correct my assumption, otherwise?

@kevn it’s really about looms. If someone doesn’t quite believe in the concept, or they just do not have the funds to put together a full cable loom, yes start with power cords first. Then do speaker cables as that is a loom of two unless you are bi-wiring, them finish with Interconnects. Ironically, it will be the last cables you replace that aren’t part of the loom that will be perceived as making the greatest difference. 

You can make DIY Cords and fuses as good, if not better than most manufacturers. Pennies on the dollars, and it’s a lot of fun to experiment on your own. .

Copper foils for USB, and XLR. Solid for everything else.

Mineral oil+graphene+silicon dioxide for fuse dampeners.

DIY DIY DIY DIY. At least for the ones that are good with tools.

I bet there is an astounding percentage of hermit Agoners. Wow. To the OP, Speakers and source components first. But reality is, that is a MASSIVE variable with all number of possibilities. No easy answer. Power has to be second. If power sucks, so does everything else. Speaker cables next, then on down the line. And I too disagree that the entire loom much match, plenty of people making great music with a variety of cables.
