So, no, you didn't actually perform a real, measurable test that would show the dB increase you claim happened. Instead, you're saying that you can tell what a 1, 2, or 3 dB change sounds like. I find this hard to believe. Make this claim when you can back it up with hard evidence. Until then, it's exactly as you said, an "illusion" of difference. You're expecting to hear a difference so you make it up. Positive or negative.
I didn't expect to hear a difference in volume after I added the books to my system, I regret I didn't do it earlier because that was exactly what my system needed.
1dB makes a huge difference. I know how it sounds like because for a year I used -1dB of my computer and then changed to 0 and I got fatigue. My Cary CD transport was always 1dB louder than my computer and when switching back and forth the difference was big.
I have done a quick
blind test and I guessed within 0.3dB. If I would do a long-term volume test I would probably be accurate within 0.2dB.
You completely contradicted yourself in the opening line with everything else you than state. The power cable is NOT where the sound comes from so how can it create (as an illusion) "more low-level detail and speed" in the sound?
BTW, speed of light is speed of light. You can't have slower speed of light. This measurement is well established and either it is or isn't the speed of light.
What 3 signals are you passing through your power cable?
You slowed down your Valhalla cables and now you get more speed?
"Scotty, I need more speed!"
"Capt'n, I've slowed 'er down. She should go faster now!"
"And Capt'n, you do know it's a cable. It doesn't move. The copper can only restrict the flow if it isn't correctly made. Once it's made correctly, the signal only goes so fast."
Honestly, come back to reality. Are you sure Ming isn't after you for the "imex", or is the Collective looking for you?
Resistance is futile.
Ignorance is self-imposed.

The power cord isn't in the path of the signal, it just changes the flavor of juice inside the capacitor before it gets pumped out to the components on the green board.
I like to manipulate the power supply with the silver plating of Valhalla cable, it removes some low-level detail compared to stock cable but it makes it sound cleaner because the low-level noise is covered in snow. It makes it sound like real life and I can listen for hours! It's similar to tubes but without the sacrifice of speed.
All power cords color the sound, to get neutral sound you need to use the same gauge as the apartment wiring. But it sounded too boring so I colored the sound with Valhalla instead. I modified the Valhalla closer to the size of the apartment wiring and it gave more low-level detail than the fat Valhalla.
The thicker the power cord is the heavier and slower the music sounds like. With a thinner cable you get more speed. Stock cable is 18awg and it has lot of speed compared to aftermarket power cords. I have a whole box full of stock cables under my bed.
I like them more than PS Audio Statement power cord, because they are more neutral. Adding the Statement cable after apartment wiring makes it slower and heavier with the illusion of more bass, the sound signature was easy to hear in my video blind test.
Speed of light doesn't matter, it's just marketing the companies use. Nordost also says on their website that their cables are neutral, but that's not true, they are the most colored cables I have heard. Valhalla gives the illusion of neutrality because it removes low-level detail which makes it sound like real life. The Valhalla interconnect removes attack and decay which makes it sound colder with tighter transients, but it's still smooth. It emphasizes the highs but it's not real, it's fake. A deeper silver plating depth gives more coloration, I have switched from Valhalla's 78microns to Valkyrja's 60microns silver plating. It gave less tightness but more low-level detail. The difference was bigger than I expected.
