True or False?


Many high-end manufactures deny the benefits of tweaking their components with upgraded power cables, fuses, etc. We all can agree that even the best speakers respond to room placement but is it true or not true in (your experiences) that the better your audio components are, the less they respond to various tweaks?

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!!!!

Instead of asking inane questions on a forum to arrive at a solution you should read inane articles on an inane webzine. 
FALSE, the cost doesn't matter. Tweaks are useless in an inexpensive, moderate or expensive system.
