I’ve changed a lot of cables in my system.
Speaker cables, interconnects, power cables, digital cables — and, increasingly, the “other stuff” that lives in the same universe: tuning tweaks like a LAN silencer or absorption feet. If there’s something between the music source and my ears, chances are I’ve questioned it at least once.
And yes, I know how this sounds.
The argument about whether cables make a difference is basically as old as hi-fi itself. It’s also one of those discussions where people talk past each other. One side wants measurements, physics, and repeatability. The other side talks about lived experience, attention, and the way music feels in a room. Both sides have a point — and both sides can get a bit… intense.
I’m not here to settle any of it. Honestly, I don’t think I’m qualified to add anything “final” to that argument.
What I can offer is much simpler: what I did, what I thought I heard, what surprised me, and what I learned about my own brain along the way.
The uncomfortable part: yes, I know about bias
Before we get into the cable drawer: I’m aware of the psychological traps.
Expectation bias is real. Confirmation bias is real. If I spend money on something, my brain wants a reward. If a cable looks premium and feels heavy, my brain already starts narrating improvements before I press play. Even the effort of swapping things around can create its own “well, that was worth it” effect.
And even if all of that weren’t true: most changes in cables and tuning are not the kind of thing you notice like switching speakers, or moving from a bad DAC to a good one. It’s rarely night-and-day. It’s more like… a slight change in how the system breathes. A small shift in tone. An adjustment in how “tight” or “relaxed” things feel.
So why did I keep doing it?
Because those tiny changes, over time, started stacking. And eventually the system ended up in a place that felt more “right” to me — whether that’s physics, perception, or some combination of both.
The money part: diminishing returns hits early (especially for cables)
There’s one thing almost everyone in hi-fi agrees on: the law of diminishing returns is real.
And I think for every audiophile there’s a point where the amount of money a component sells for becomes… silly. That point is different for everyone, but for cables — at least for me — it happens rather early.
I understand why complex devices like amplifiers, DACs, or speakers can cost thousands. There’s engineering, parts, housings, R&D, production tolerances, and in many cases genuinely complicated work happening inside those boxes.
But a power cable that costs hundreds? That’s where my brain has always slammed the brakes. In the end, it’s still a power cable. In principle, it does the same thing as the one that came for free in the box.
My own journey has taught me that it’s not always that simple — and that there can be value in well-made cables. Materials, shielding, connectors, build quality, and practical aspects matter more than I expected.
But I also believe this strongly: the point where returns start to diminish seriously is surprisingly early. Past a certain point, you’re paying a lot for very small shifts — and the shifts are often the kind you only notice if you’re already deep into “system balance” territory.
What I changed (and what it felt like)
To keep this grounded, I’m going to break it down into the usual categories: speaker cables, interconnects, power cables, digital cables — and also tuning. I’m not going to claim universal truths here — only patterns I noticed in my room, with my gear, and with my preferences.
1) Speaker cables: the “foundation” changes (and my actual swap)
Speaker cables were the first category where I felt like changes could be noticeable — but only under two conditions:
- the system was already fairly dialed in
- and I listened long enough to stop hunting for differences
In my case, the concrete swap was from Inakustik LS 1002 to Inakustik LS 603.
To be fair, this wasn’t a huge change — neither in “level” nor in brand. Same company, broadly similar intent, and not exactly a jump from a random thin wire to something serious. Maybe that’s exactly why the improvement was rather subtle.
What I usually noticed here wasn’t “more detail” in a spectacular way. It was more like a gentle shift in presentation:
- sometimes a bit more body in the lower mids
- sometimes slightly sharper edges on transients
- sometimes a touch more calm or control in bass notes
The annoying truth: it was rarely obvious in the first 20 seconds. It showed up over a longer listening session — especially when going back to the previous cable felt a little less enjoyable, even if I couldn’t write a heroic description of why.
What’s interesting is that the bigger “step” for me came earlier. Before the LS 1002, I used ELAC Sensible cables — a very basic, but well-made copper cable. That change felt bigger, even though the differences were along the same lines as described above. Not different in kind — just more noticeable in degree.
If there’s one practical takeaway from my own swapping: speaker cables can influence the system’s “overall posture,” but the biggest shifts tend to happen when you move between more different “tiers” of cable — not when you upgrade within the same family.
2) Interconnects: the one swap that genuinely surprised me
Interconnects (RCA/XLR) are where I experienced the most dramatic cable change — and it happened almost by accident.
When I moved away from my all-in-one setup to a separate streamer, I suddenly had to introduce analog RCA interconnects into the chain. At first I used the Inakustik Referenz NF-102. They worked perfectly fine in a technical sense — nothing was “wrong,” no obvious flaws, no noise, no drama.
But the system consistently felt like it was missing body. The presentation was clean, but a bit too lean for my taste. Music had detail, but not enough weight.
Then I tried AudioQuest Yukon.
And that was one of those rare moments in this hobby where you don’t need to squint, concentrate, or convince yourself. The system sounded noticeably richer — more filled out, more substantial, more satisfying. It wasn’t a subtle “maybe” change. It was a clear shift in how the whole system presented music, and it ended up being the single biggest cable-related improvement I’ve experienced so far.
The fun twist: the Inakustik NF-102 didn’t get thrown into the “never again” drawer. They found a second life in my secondary system, where they actually work great. Which, again, brings me back to the theme I keep running into with cables:
In the end, it’s often not about “good” or “bad.” It’s about synergy — matching the cable to the rest of the chain, the room, and your own preferences.
3) Power cables and conditioning: where things got expensive (and oddly convincing)
Power was the area where my skepticism lasted the longest — and where my experiments got the most… involved.
My first step into power cables was an IsoTek Premier Evo. I bought one for my amplifier and I thought it had a little impact. Not much, and if I’m honest, I’m not sure I could reliably pick it out in a proper double-blind test. It was one of those changes that felt plausible but also dangerously close to “maybe I just want it to be better.”
Then I bought an AudioQuest NRG-Y for my streamer — and that one was different.
The effect wasn’t night-and-day, but it was noticeably larger than the IsoTek experiment: the music felt a bit more dynamic, there seemed to be more space between instruments, and the whole presentation had a touch more authority. Still small improvements, still subtle in absolute terms — but now subtle in a way that felt repeatable over multiple sessions.
That experience was basically the gateway drug. I started upgrading one power cable at a time in the system to AudioQuest.
And around that point, I also fell into the next rabbit hole: power conditioning.
At first, I used a “normal” (non-audiophile) filtered power strip from a well-known mainstream manufacturer. It did what it should do — gave me outlets, cleaned up cable management, maybe reduced some obvious nasties — but it didn’t feel like a clear “hi-fi upgrade.”
So I picked up a Dynavox X4000 on the used market.
When I plugged the streamer into it, the impact was immediate. The problem was: I wasn’t sure I liked it. It was one of those changes where you can tell something is happening, but you’re not sure if it’s a net positive or just different. That was an important learning moment for me, because it reminded me that “audible” isn’t the same as “better.”
Since I had good experiences with the AudioQuest cable direction, I decided to go further and bought an AudioQuest Niagara 1200 power conditioner — again, used.
And that had a quite audible impact.
It was like the NRG-Y effect, but scaled up: more ease, more authority, a calmer background, and that same sense of improved space and dynamics — just more pronounced. Where the Dynavox felt like “something is happening,” the Niagara felt like “okay, I can actually follow this.”
From there, I gradually plugged more components into the Niagara, using AudioQuest NRG-Y cables across the system. The most noticeable improvements came from the amplifier, DAC, and streamer — basically the core of the chain.
The last step — and the one that was hardest to justify to myself — was the AudioQuest Monsoon power cable, used to connect the Niagara 1200 to the wall. That’s where even I have to laugh a little, because the “in principle it does the same thing” argument gets very loud in my head at that point.
But if I’m staying true to what I experienced: I do think the investment into power (cables + conditioning) improved my system.
Whether the amount of money spent is worth it is a completely personal call. For me, buying used made the whole thing far easier to swallow — and it also helped me experiment without feeling like I needed to “defend” the purchase afterwards.
And maybe that’s the healthiest part of this whole power saga: I’m still skeptical, still aware of bias, but also willing to admit when something consistently nudges the system in the right direction — even if I can’t wrap it in a neat, universal explanation.
4) Digital cables: where my skepticism survives (but not in every corner)
Digital cables are still the category where my inner rationalist feels safest. In the end, it’s all ones and zeros — so I’ve always had doubts here, and honestly… I’m still not fully convinced, at least not in every category.
To get this out of the way: yes, I bought an “audiophile” LAN cable — the AudioQuest Cinnamon. Did it make a difference? I’m not sure. If it did, it was certainly minor, and not the kind of thing I’d confidently defend in a serious blind test.
Same story with USB. I tried a nicer USB cable and didn’t really hear a difference.
But I bought both of them used, they’re sturdy, they look good, and they’re pleasant to handle and route. So… why not. Even if the sonic impact is questionable, the practical and aesthetic side is real.
Now here’s the twist: there were digital cable changes that surprised me more than I expected — specifically coax (SPDIF) and optical (Toslink).
In both cases, moving from “random cheap cable” to better-built, more audiophile-grade cables made a clear difference in my system. Not night-and-day, but clear enough that it didn’t feel like I had to convince myself.
Coax: small, consistent differences — even between “good” ones
Among coax cables, I heard differences even when comparing “decent” options:
- Inakustik Premium Coax
- Van den Hul The Digital Coupler
- AudioQuest Cinnamon (coax)
They didn’t transform the sound, but they did nudge it in repeatable ways. The Van den Hul felt a bit warmer, while the AudioQuest came across as more spacious. Again: small changes, but noticeable.
Optical: the unexpectedly obvious one
The bigger surprise was optical. Changing from a cheap Toslink cable to the Inakustik Exzellenz cleaned up the sound significantly. Cleaner, clearer — less “hash,” less blur around edges. It was one of those swaps where you don’t immediately reach for poetic audiophile vocabulary — you just notice that things sound more sorted.
So where do I land on digital cables?
LAN and USB: still skeptical, still “maybe, but probably minor.”
Coax and optical: unexpectedly more audible in my setup, with differences that felt small-but-real.
And once again, that word comes back: synergy. Digital shouldn’t be messy, but real-world systems often are — and sometimes the “shouldn’t matter” category ends up being exactly where a small, well-made change becomes surprisingly easy to hear.
The part I didn’t expect: it’s not one cable, it’s the whole balance
Most cable and tuning changes are tiny on their own — but they can push the system in a direction.
If you do ten tiny things that all push the system toward “slightly brighter,” you’ll eventually get a system that’s just… bright. Same with warmth, smoothness, punch, or calmness.
That’s where I think “cables add up” can be true without turning into superstition. Not because each cable is a miracle, but because you’re constantly nudging the system’s overall balance.
Even if some of it is perceptual, the direction still matters — because the goal isn’t to win an argument. The goal is to enjoy listening more.
So… was it physics or was it my brain?
Honestly?
Probably both.
I don’t trust myself enough to declare victory on the “objective truth” front. I also don’t distrust my own experience enough to throw it all away as placebo. Hi-fi is a hobby where perception is the whole point — and where our perception is also the most unreliable instrument in the room.
So my stance today is simple:
- I don’t claim cables are universally transformative
- I do think small changes can influence the overall balance in a system
- and I think the only honest approach is to experiment, stay humble, and keep your wallet in check
Because the moment you stop listening to music and start listening only to your own expectations… you’ve lost the plot.
And there’s one more aspect that’s unquestionably real, independent from any sound discussion: the look and feel. If cables are visible in your setup, nice thick runs with solid connectors and a clean braid simply look a lot cooler. There’s something satisfying about well-made cables you can actually handle, route cleanly, and feel like they belong in the system — even before a single note plays.
What I’m doing going forward
I’m not done experimenting. I’m just trying to do it more intentionally now.
I want changes to be:
- reversible
- reasonable in cost
- evaluated over longer listening sessions
- and judged by one metric: “Do I enjoy music more?”
And if the answer is yes — even if my brain helped a little — I can live with that.
