That reminds me, I have to go in to the dealership to get my muffler bearing re-surfaced on my FR-S. It's $700, but the guy said it's critical and will drastically increase engine life. :D
Probably, when you mix Toyota with Subaru, you get weirdness.
Yep. I have three Scions: A Toyota, a Subaru and a Mazda (xB, FR-S and iA).:D

BTW, all three are a lot more reliable than my Silverado Z71.

But it is not just a wire (or cable). It is a wire/cable that connects an amplifier to a loudspeaker. All must be included.. There is at least one (respected?) amplifier where the wrong wire/cable leads to instability. 'Just a wire'?

For those who cannot hear a difference, or will never accept that there can be a difference, please accept that there are others that can hear a difference, or at least think that they can, and are happy. :D
Its wire. If an amplifier is so unstable that negligible capacitance and a minute resistance affects its operation, that speaks volumes about the poor design of the amp, not the physical properties of the wire.

Many people PERCEIVE a difference. or, as you say, think they can hear a difference - and that’s fine. All power to them I say if they derive enjoyment from it. But they need to understand that their perception has the same evidence base as those who perceive spirits and claim they can hear messages from the dead ie none whatsoever.
well, I have heard a difference, and I am the most un-spiritual person on God's earth...!

I am very surprised (well, not really!) at people's reactions to others of different opinions. Guys, people have different opinions, doesn't make them any different to you, except their opinions. So lets have respect, and a realisation that (in general) it is a free world, where civilised people can have different opinions without prejudice from others. Ta.

All fine.
Opinions, everyone's got one, of course.
Some are more vocal about it than others.
However, when opinions show bias due to misinformation or ignorance of a given subject, it's not unreasonable to make an attempt to educate the person.

Spinner45, exactly who is trying to educate whom here?

People told me that capacitance in cables is bunkum. I showed the scientific reasoning and research behind it. Indeed, when I was challenged that when you draw a circuit diagram of an amp to a speaker, no capacitance or inductance exists. Copper is copper, electrons "don't care", etc. However, I explained where these components should be put, and indeed, here in Figure 1 on page 50 is corroboration of that from Professor Greiner, who I have to say is likely to be more qualified on the subject than anyone on this forum:
https://www.acmebass.com/archive_files/ ... 8-1989.pdf

In the thread, I was lambasted, and shouted down with talk about poop, and cows, and coat hangers.

So, who's trying to educate whom, and who has bias based on lack of knowledge? (and I remind folks that I hold a degree and PhD in physics and did actually teach undergraduate experimental physics and electronics at Cambridge University (albeit in the 1990s).

I actually believe you have heard a difference. However, I don't know how far out of adjustment it had to be before you did hear this difference. I have no doubt that if I adjusted the VTA on the fly on my 120 I'd eventually hear a difference. The question really is, how far out of adjustment does it have to be before I notice that difference?

Perhaps the answer to Needler's question can also be related to VTF. Increasing VTF by 0.2g on my AT-440MLb, improves the sound noticeably. Wouldn't changing VTF create an effective change of VTA?

As for any capacitance of speaker wiring, considering home use, and at audio frequencies, it's not anything to fuss about nor even discuss.
Wire size, on the other hand, should be considered, particularly if long runs are involved, to prevent losses.
To a lot of people, wire is wire, and they have no technical knowlege of differences, or quality.

No, you still don't understand my complaint. Capacitance is a property. Capacitors are a manufactured component.

At pF/m capacitance (unless you're going to braid something, and that's a whole different issue), I agree.

No not true we, actually it was me said capacitance in cables unless very high as for the 3 or 4 meter runs in speaker wire in domestic situations capacitance is really a non issue, you have to go out of your way and do something stupid like the crazy cat 5 speaker wires to make capacitance an issue that is what I said. Also again I said similar re resistance and inductance and we discussed impedance again 3-4m long normal wire not a problem, if we are wiring a concert hall maybe but not average hifi in lounge. Nobody said any of this was bunkum we said it was for audio frequencies for domestic lengths not he same thing.
The cow poop and coat hangers was VE members having a very VE light hearted joke after a very very long 19 page thread not aimed at anyone just a bit of fun.

Yep. The only test I've seen that discusses an actual difference in sound is one that tests against really thin wire. Who uses 24 gauge wire in a remotely serious hi-fi setup? It's almost like it was a bogus test that was done solely so that people could claim that there is a test out there showing that speaker wire matters no matter what argument they are making regarding speaker wire. "There is a test that PROVES speaker wire matters!"

They should have done it with a long run of ear-bud wire. :)

In one of my bands we had a bank of four 150 watt lights in a light bar. The guitar player was an electrician. The entire setup's power wire was cat-5 wire. I thought he was nuts and, actually, he was, but he was right about whether the wire could handle it. But there are other reasons you don't want to use cat-5. The connectors, for starters...
