Ever notice how the one thing critics of investing in upgrades to power components have in common is . . . NONE of them have actually used any of the suggested upgrades?
I am a long time audio fan, going back to when RTR decks were standard equipment. I recently reached a point where I am able to equip my small listening room with decent quality components, I would describe as entry-level audiophile grade, and my system investment is around 10K (not including headphones which is a whole other topic).
When I reached that level, I decided to take a look at upgrading cables and power, including a used empower power conditioner. I'll skip the endless technical debates and just cut to the chase by stating that the improvement is not subtle, its dramatic.
The adamant "wires are wires and bits are bits" trolls who claim that investing in cable and power component upgrades is "nuts" are simply highlighting their complete lack of understanding as to how actual MUSIC (sound) is transmitted to the human ear, NOT to test instrument measurements.. Simply put - all music is sound waves (analog) and all audio equipment runs on electricity (the electromagnetic field) and both of these have countless ways of interfering with each other and degrading the final sound that reaches the listeners' ears. Minimizing that interference is crucial to the listening experience.
That said, I wouldn't necessarily go all in on th4ese upgrades up-front, but once you've made a decision on quality components, not supporting them with upgraded cables and power components is truly "nuts".
