Yes. Especially as we age. By the time we can afford the fancy stuff, our ears are toast anyway.
Take it from a EE, this is stupid stupid stupid stupid stupid. I could go on, which is how stupid it is.


My best friend in college was one of my TAs, he was an Oxford undergrad who was earning his Masters and PhD at Texas in Acoustical Engineering.  By far the smartest electrical engineer I've ever met.  His specialty was acoustics, but he knew every bit as much as I did about digital design, computer programming, IC design and manufacturing, and everything else.

Anyway, during his time at Texas, he did extensive research on "monster cables" and various other brands.  He worked on some of that with another friend of ours who also specialized in acoustics, also earning his graduate degrees from UT, after receiving his undergrad from MIT.

You would obviously NOT be surprised at their findings and conclusions about the relative performance and expense between those premium brands they tested, versus other inexpensive brands, and also versus random conductors like lamp cord and romex.

The issue with things like speaker cables is confirmation bias unless you do a blind study, and even then it's qualitative.  I might prefer the sound from cheap cables and you might prefer the other, but which of us is right?  We both are, but I end up paying less.

I use Monster type cables with good connectors, that makes sense to me, they are lightly shielded.  Maybe if I used expensive cables I could hear some difference, but is it better?  It's subjective, and nothing is as good as the real thing, a live performance (I'm talking classical music, rock often is so loud you can tell anyway).

No, there are definitely tests you can do that would tell you the performance of the cable. 

Essentially it's simple... What you get at the speaker end of the cable should be as close to identical as what you put in at the source end of the cable. 

You can measure a waveform in the time domain with an oscilloscope, or measure it in the frequency domain with a spectrum analyzer, but simple testing would be to run various types of signals through and see how clean they come out on the other end. 

You want a speaker wire to be as free from distortion and interference as possible. 

Just about everything I've ever read on the subject says that as long as you have an adequate gauge wire for the distance you're running and the power you're pushing through it, very little else matters, including cost.

Yup.

Lamp cord turns out to be a better speaker wire than everything on the market that is marketed as speaker wire.  Heavier gauge.  Really all that matters.

Truthfully, I'd like to get a halfway decent stereo system. 

But at the same time, I mostly listen to streaming music, so the quality level doesn't justify it. 

So if I do it, I will be absolutely looking at a halfway decent system. A couple hundred on a multichannel AV receiver, a couple hundred on speakers and subwoofer, and done. Spend enough that I can get decent volume, decent midrange and bass, but there's no source material I'm likely to use that justifies spending thousands. 

That said, even if I had all my audio in lossless FLAC encoding, nothing justifies stupid overspending on speaker cables.

Yes, you are right, one could measure the wave form input with the wave form at the end of the cables, I hadn't thought of that.  I was more thinking of the aural experience, some humans might prefer the more distorted wave forms.  Shielding apparently is a "thing", for some.  

I bought the wife a sound bar with a wireless subwoofer a while back, the wireless connection would pick up ambient distortion fairly often, lightning was one item.  I can see that an unshielded wire could pick up ambient foreign signals.

I personally would not spend money on high end speaker cables, but obviously they exist, and some do.  As I say, if you invest say $50 K in the system, another $2K is not inherently out of balance with your budget.  My system is more in the $4 K area, which I think just about maxes out your return.

For most folks, I think a half decent sound bar is a good way to go for TV/movies and even music in general.

My wife also has this tiny speaker she uses for streaming fairly often, it looks like a gimmick, but as long as the volume is fairly low it's really adequate.

BTW an audiophile will debate to the death about the value of their speaker wire, even though they're wrong.

At least speaker wire is analog, so you can have a debate about fidelity. But as for any digital cable, you should NEVER EVER even consider overpaying. 

Digital signals don't have to worry about fidelity--to a point. You either have a good enough signal to reconstruct the data stream PERFECTLY, or you don't. Cables are binary, either good or bad. And bad is bad...

As a cable company says here regarding HDMI cables: https://www.bluejeanscable.com/articles/premium-hdmi-cable.htm


Quote
It remains the case under HDMI 2.0 as before that this isn't a subtle thing; if a cable is failing, you will see the failure manifested, in the great majority of cases, as one of the following, in order of severity:

(1) "Sparkles": individual dropped-out pixels, or
(2) "Line" dropouts where a whole line of video, or the rightward portion, drops out, or
(3) Intermittently flashing or jumping picture, indicating that so much picture data is being lost that the display is losing sync, or
(4) No picture.

These types of issues are what to look for. If you don't see them, your cable is doing fine with the signal currently being run through it. The effect won't be subtle -- it's not about qualitative aspects of the image like shade detail, contrast, and the like.
If your HDMI cable works, spending an extra $10 or $100 for a "better" cable won't do squat for you.

I think high end audiophiles like to feel superior to the rest of us, and like spending money on their hobby.

We've all seen old Honda Civics with very expensive 22" rims and loud "mufflers"/exhaust systems, riced up.  They sound horrible and they often have automatic transmissions and are still as slow as an old Civic would be standard.  Or cars with the backseat taken out and replaced with a subwoofer that distorts more than it speaks.

Long ago, I would drop by various audio shops and listen to their new gear, they could do side by side etc., and I could hear differences, but couldn't really say one was better than the other.  I was/am a Phillistine.

Wine can be the same thing.

But when you're looking at stereos, you want hi-fi right? High fidelity.

fidelity
[ fi-del-i-tee, fahy- ]SHOW IPA



See synonyms for fidelity on Thesaurus.com
📙 Middle School Level



noun, plural fi·del·i·ties.
  • strict observance of promises, duties, etc.:a servant's fidelity.
  • loyalty:fidelity to one's country.
  • conjugal faithfulness.
  • adherence to fact or detail.
  • accuracy; exactness:The speech was transcribed with great fidelity.
  • AudioVideothe degree of accuracy with which sound or images are recorded or reproduced.
In audio, you don't want the wire to distort the signal to make it sound "better". You want the signal that was recorded to come out of your speaker. In no other area of audio that I'm aware of do audiophiles accept that distortion is preferred.

Speaker cable is a bit different from a lot of the interconnect cables we handle, in several respects. Because speakers are driven at low impedance (typically 4 or 8 ohms) and high current, speaker cables are, for all practical purposes, immune from interference from EMI or RFI, so shielding isn't required. The low impedance of the circuit, meanwhile, makes capacitance, which can be an issue in high-impedance line or microphone-level connections practically irrelevant. The biggest issue in speaker cables, from the point of view of sound quality, is simply conductivity; the lower the resistance of the cable, the lower the contribution of the speaker cable's resistance to the damping factor, and the flatter the frequency response will be. While one can spend thousands of dollars on exotic speaker cable, in the end analysis, it's the sheer conductivity of the cable, and (barring a really odd design, which may introduce various undesirable effects) little else that matters. The answer to keeping conductivity high is simple: the larger the wire, the lower the resistance, and the higher the conductivity.

I will say that one area where this might not be true is in car audio. Wire routing in a car can sometimes cause issues because of significant amounts of power running through the vehicle. However I think a good portion of this isn't even the speaker wire part, it's running the power cables to an amplifier in a way to avoid interference, and routing things like low-voltage preamp wires from the receiver to the amplifier in an area that it won't be subject to interference or crosstalk.

Maybe $2K for speaker wire isn't out of balance with the budget for a $50K audio system. It's still a complete and total waste of money, beyond the psychological aspect that it buys you, and the bragging rights you get being able to tell people you spent $2K on speaker wire.

Of course, that bragging will not have the desired effect on guys like me and @utee94 lol...

Interesting, I had guessed some shielding MIGHT be useful with cables, but apparently not, outside perhaps some extreme situation.

I have my old receiver in my office with some small speakers I hooked up with very thin cables, I didn't have anything else, and I don't listen to much here.  They work.

We all know "mavens" who will try and eek out even symbolic "performance" in a hobby thing (like college football and ribs).
