I have slowly been putting my system together over the last decade, mainly due to cost. Two years ago decided to have my room rewired (10 g quality copper twist) from main drop, including a new electrical panel, upgraded grounding, and electrical outlets. The best money I have spent on my system - especially for the price point...cheaper then my power cables ( DH Labs). It made every component in my system sound better...instantly, and more noticeable than any other component or upgrade I have done. Best bang-for the buck you can do for your system.
Why we (often) upgrade the wrong things (first) and ignore the important things
I continue to be impressed by this person. See:

He argues for applying a bottleneck principle to audio upgrades: system performance is always capped by its dominant constraint, so upgrading any non-limiting component produces only incremental refinement, not genuine improvement.
The hierarchy of constraints, roughly in descending magnitude, runs: room acoustics and speaker placement (capable of 10–20 dB swings), amplifier headroom and load stability, gain structure alignment, DAC output characteristics, and finally cables. Most audiophile upgrade behavior inverts this hierarchy — people swap DACs and cables because they’re easy, not because they’re limiting.
The gist is a distinction between **audible change** and **ceiling removal**. Any swap can produce a detectable difference; only removing the dominant constraint raises the system’s maximum capability.
He gives a way to test it. When we remove a constraint, that feels unmistakable and immediate — dynamics expand, you stop gear-monitoring and just listen — whereas novelty-driven changes require effortful attention to detect and fade in significance.
Room treatment and gain-structure analysis are effortful; cable swaps are not. Making this worse are the ways we mis-focus on novelty, which amplifies perceived differences. We think we’ve made a structural improvement but we have not, actually.
