No one actually knows how to lculate what speaker cable they need


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

On the other hand, who really cares what SPICE says about bi wiring. None other than John Atkinson of Stereophile reports otherwise. So, this appears to be one of those talkers vs doers type arguments. 😬 Or, perhaps a measurements vs listener argument. 😛

“Some audiophiles feel that bi-wiring produces an audible improvement over standard single cabling. For example, John Atkinson, writing in Stereophile, states that he observes "subtle but important" differences, particularly in reduction of treble hardness and improvement in bass control in one review.”

And this from Definitive Technology,

“Does doubling the connections double the sound quality?

Bi-wiring is intended to minimize impedance differences between high and low frequencies and its impact on the overall sound you experience. The result is an improvement in the midrange that many enthusiasts believe is significant enough to justify running the additional cable. You may not double the quality of your playback, but you will likely notice a major boost in clarity.”

There’s also this from Polk Audio, who knows something about speakers,

”What is it?

Bi-wiring is the using separate speaker wire connections to split the signal between high and low frequencies.

What does it accomplish?

The theory behind bi-wiring is that it can elevate a great sounding speaker and produce subtle, enjoyable, improvements in overall sound quality. In a sense, bi-wiring is to speaker connections as “star grounding” is to electronics connections.

When a piece of audio equipment uses a single circuit grounding point for all electronic sections as opposed to connecting them in a “daisy-chain” fashion, this is referred to as “star grounding.” The integrity of each ground path is maintained by individual connections to a low impedance point.

The same concept is applied when bi-wiring your audio system. Each “section” of your speaker is independently connected to the low impedance point (output transistors) in your receiver or amplifier. The effects of bi-wiring have been described as “lifting a veil from the mid-range” and that “voices seem clearer, more distinct, and less muffled.””


Mr. keppertup

Thanks for the photos. As it does the job, I can’t comment on functionality :-)

May I please comment on your workmanship? Ref. to your 2nd picture, that the two ends can be seen better:

On Spade side - you have a thread that was not captured by the crimp and is lose. Spades need maintenance as the binding post loose grip in time. This end could use a short shrinking sleeve to cover some of the cable and some of the exposed cooper sleeve. For the safety and for the good looking.

Your other end, with the short low gauge wire stacked in the 0 AWG: is a nice idea.

I’m not so sure if that would hold in the long term, if the 0 AWG weight is hanging on it.

Here is mine for ref. was posted on page 2 of this thread:

@geoffkait , absolutely. While the logic and absolute-ness (in audio, indeed!) might not be agreed on by everyone, I'm an advocate of trying it and seeing how I get on. If bi-wiring has claims to work (ignoring any bi-amping, whether active or passive) then swapping the cable for one double thick run instead of two thinner runs should achive a similar effect. Maybe that's what's being seen here? Either way, agreeing that bi-wiring might work but this can't seems like a contradictory argument.

Again, I'm putting aside the argument presentation, the use of DF as a variable, and the maths involved in the calculation. I'm just talking about increasing the cable size, which is all we're really doing.

@b4icu, can we see inside those cables to see what's under the heat shrink? I'd be interested in to see how you've stepped down from 0 awg to bananas. Doesn't the thinner bridge cable act as a limiter? The weak link in the chain, if you will?


Mr. geoffkait
You,  Mr. John Atkinson or others you may quote, never got the speaker cable thing right from the first time! so they added a second wire, of the same gauge to the single and the sound improved...
This is what this thread is all about. As if you read this thread thoroughly, you could get a slight impression of Mr. keppertup on his sharing of implementing this idea. A beautiful one.

I'm sure you would rather keep sticking to your false ideas and a limited sound quality (you most likely call high end) because Mr. John Atkinson or others said so. Enjoy both.

If you would get that, many of your falls accusations could be saved, with many of your postures posts and so you would earn less points...Sorry about that.

I've seen you on a parallel thread about the burn in, and I felt really bad for you.

 

Mr. conradnash

Sorry, the one you see serves my friend in Vancouver BC. If you live nearby, I can get you acquainted.

I have no pictures of that as I never thought to be asked for.

The wire between the thick 0 AWG cable and the banana plug is of 8 AWG. I really believe that this banana plug is the best possible electrical and physical way to connect between it and a binding post.

The banana plug is soldered thoroughly to that 8 AWG wire. 100% of its inside perimeter and 100% of the 8 AWG wire for the entire common length (about 2cm long).

The other end was soldered to the spade (cable shoe) that is of way thicker and more firm than the one Mr. keppertup has. It is soldered on both sides of the shoe (over the center hole). The shoe is crimped on two presses with a 70 DIN size tool.

Than the ends were worn, with a black sleeve (larger diameter) on the thick cable, the shoe and the edge of the 8 AWG cable. A second sleeve (white) is covering that edge and all the 8 AWG wire and secures (permanently) the banana plug sleeve from open.

This structure ensures the best electrical and mechanical construction, and it is very strong. It took me a while to figure it out…For the record, I also have a perfect solution to use two and four 0 AWG wires in one cable, for those who really need that.
