Power Cords - Just Say Yes

"Everything matters"

Not to everyone as you point out though, plus no two things to exactly the same extent, so there is a pecking order in general to what matters most or least

"everything has a sonic signature and contributes to the end result we hear in our listening rooms"

I agree with this theoretically, but practically there is way more that matters little or is less or insignificant than the things that matter most. Time is best spent getting the things that matter most correct first. I think a lot of people are hoodwinked into wasting time dealing with less or insignificant issues before the time is right (if it matters at all to them in the end). That can be a huge wate of time as pointed out. SO it is important to put all things in proper perspective and order of significance.

"Including the room itself, which is so often neglected."

That is a big one, perhaps even #1, that is often neglected.

"I also believe that the majority of those who state loudly that powercables (or whatever) CAN'T sound different will NEVER hear a difference, because they don't want to"

I want to hear a difference in wire and all the other improvements that tweaks bring, and I have good ears. But with all the Supernovas going on in the Milky Way, and the Sun making all that racket with Atomic Fusion, I can barely hear my speakers, let alone wire!

Lacee..well put. question..do you really have 5 ongoing systems as your 'System' link shows...?..if you do ..and you're trying to tweak all of them ..you are one very busy audiophile...!!

No I don't have five systems, just the on going changes over the past few years to my main dedicated 2 channel system.
I suppose I should update.

What has remained constant are the Shunyata Annaconda power cords and Hydra conditioner for the front end gear.

Those power cords don't hinder the performance of anything they've been plugged into.This is also the system with 2 dedicated 20 amp lines- one for the power amps and one for the front end.I also use HifI supreme fuses in the Steelhead and the Acoustat servo amps.
Other recent upgrades were top of the line Furtech RCA on the amps, GTX receptacles,Top tier Furtech IEC on the amps and Furutech rca males on the 3 wires from each speaker.

The more I do the better it gets, but I need to get some real room treatment on my walls.

The main audio only large listening room has some ASC quarter round traps and some DIY wall panels.

I've spent a fair amount of effort on getting the power cleaned up to my gear, I like what the Furutech parts have done.
But they weren't the cheap ones,again, do it right once.

I have a smaller HT set up in an adjoining room that has 4 Magnepan MMGW on wall speakers, their centre speaker,a Depth sub a Yamamha reciever as a surround processor and a 5 channel Emotiva power amp, which is a real improvement over the Yamaha receiver.I may move up to an Emotiva pre pro in the future.

This room is devoid of room tuning. Except for a Furman IT 15 amp balanced power conditioner and a few modestly expensive DIY power cords,it is tweak free.

Still enjoyable, but with a different mind set.

Yes the more solar flares there are the worse it gets.
That's why something has to be done.

Whenever I hear about a cosmic storm heading my way I duck and cover myself with my shunyata power snakes.
They are shielded afterall.
