True or False?

It is not true mainly because all components are built to a price point so that means the best parts are not always used - think how many manufacturers use V-Caps or Audio Note non-magnetic resistors, and how many components are build with copper chassis or point-to-point wiring.

Tweaks are for idol worshipers.

Yep. Tell that to the race car drivers who modify a sports car with a catch can,  Cold air intake, or shocks and suspension or Tires.  And I haven't even mentioned supercharger, or Turbo or smaller pully.  Did you spend the night at Holiday Inn? I hear a lotta experts come from there. Maybe you should quit representing your views as the final authority especially on things that I KNOW you are dead wrong.  I let it go the 1st time I saw it. But calling those who believe in tweaks "idol worshippers" is out of line. If you don't believe in tweaks, then fine. Don't do any. No problem. But quit acting like a know it all will ya. 

I don’t tweak my system.  It sounds good enough as is for me. I do use better power cords and cables.  The only tweak I have in my system is adding the GAIA footers to my speakers.  Made an impressive enough difference to warrant the $600 price although my wife has debated this with me.  

This question absolutely cannot be discovered by simple observation. One has to ask inane questions on a forum in order to arrive at a practicable solution.

What next? Whether paint color influences high end electronics more than low end electronics?

The answer should be obvious to any thinking person. But, in this place many don’t think. Worse, they don’t bother to test whether what they think is true. For that reason, obviously, answers will vary with no consensus to this question without merit.

For those prone to follow waste of life tweaks, read my Audiophile Law articles on Burn In at Dagogo.com 

In my experience different pieces of gear react to different thing.. I found the better the power supply, no mater what they are suppling react LESS to high dollar power cables. If there is a huge gain in performance because of a PC change, I'd look more at the power supply other than the cable.  I wholeheartedly believe that because I've proved to myself..

An old Mcintosh MC275 doesn't know a piece of lamp cable from a Krell PC.  WHY? Look at the power supply..

Their BRAND new stuff ALL has room for either Mac or aftermarket PC.
WHY... thing are a changing even MAC has much better cabling NOW.. Sure took long enough..

I could see a Mac fuse.. I wonder what they would price one at.. Macs aftermarket cabling is pretty reasonable. 

But even I have to look at what we're getting when we buy a Mac NOW.. I'm looking for my LAST preamp/power supply C100/1000/2000 series..

I think ALL tweaks, and even cables are a back burner issue. 
Plug it all in, clean up the mess and Prepare the room FIRST.

Speaker placement in a treated room goes a long ways to ELIMINATE future tweaks (which are patches in disguise). A real tweak is something like a real good contact enhancer... It works no matter who you are or what it's used on. 5 people will hear a difference in 5 different systems..

BUT someone that's using cabling to modify the way something sounds... NO!  I want it to reveal what's there, not HIDE, CHANGE, or exaggerate it..  REVEAL, UNMASK, SHOW ME, the beef!!!!
