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?

Most ignorant comment of the year (so far).

Question for some of the responses. Are your listening skills better in hearing the tweaks? Or is the delivery making the sound better and your listening skills are the same? Reason I ask is I have noticed this mostly in my car. I think the combination of better bandwidth they are broadcasting with and the stations using higher quality dac’s have me hearing things I can’t recall hearing just 5 years ago. I am getting older and don't think the normal progression in hearing is it gets better with age. I am in the camp of little tweaks can make a difference but don't think it can be attributed to my ears getting better.
The tweak eliminator in my experience is good room treatment.

People get off the merry-go-round of buying hardware and cables and fuses pretty quickly after they've done that.

Wise observation!

Controlling vibrations,decreasing the electrical noise floor and controlling acoustic are not "tweaks"...

They are first necessity for any working systems to reach his peak optimal...

It is called " embeddings controls" to not confuse them with secondary "tweaks" like cables, fuses, etc....
Getting the room right should be a very early step. However, with every improvement all subsequent changes are magnified as the system gets better.
