I raise my hand. I have a couple of different headphone amplifiers that have less than 0.25 ohm output impedance. <
I hereby award you a gold star!
Regards, the speaker-level example.....
The context of my comments about Roger's laughable and measureably false interconnect *test* has always been about that subject and I certainly don't use them to drive speakers. You're welcome to start a new thread about your focus of interest.
I revisited your text book example of circular reasoning and still shake my head and smile. :)
The capacitance is not significant IF the driving source is not affected by it.
If a frog had wings, he wouldn't bump his ass!
Follow Ups:
You should have continued to read in that thread. Long after you ran out of gas/understanding I elaborated on the situation more fully with Satie.
I never said the published Sanders scheme was without some possible pitfalls/variables. (I highlighted them in fact.)
But, if those variables are removed the concept is sound and you will have a valid A/B comparison between two interconnect cables.
The speaker-level example is a more real-world scheme that I thought (incorrectly) you could grasp. Take a simple, two-way speaker crossover and attach two identical full-range drivers to both outputs. The resultant output from the two drivers will be different. That should be obvious since you have a low-pass and high-pass filter driving them.
The two interconnect example is the same thing. You again have a common source coupled via two LCR filters (in this case they're both low-pass filters) to identical loads. If the LCR characteristics of those two interconnects are different enough you will hear (and measure) a difference. The reason you won't expect to hear much (if any) difference between two interconnect cables is not because the scheme is flawed...it's because there simply isn't that much difference the interconnect cables could contribute.
Hopefully you've read this far..... This is very straightforward real-world methodology. There's nothing circular about it.
I realize the ship has sailed, but more attempts at real understanding and less silly knee-jerking audiophilia would do you well.
Dave.
observing more ways you demonstrate a lack of awareness. :)You should have continued to read in that thread.
I did. Let's review the continuation, shall we?
Mr. Circular Reasoning: "The voltage source will supply exactly the same current to cable A regardless of whether the Y-connector and cable B is attached or not."
Another voice of logic (Satie): "That is not correct, which is what I am saying and which is what I don't understand why you don't see it. "
The speaker-level example is a more real-world scheme
The topic remains around interconnects. Why is that so difficult for you to understand? I'll repeat what I said in the previous post: if you want to talk about speaker level issue, then create a new post. Comprende? Do you understand Engrish?
If the LCR characteristics of those two interconnects are different enough you will hear (and measure) a difference.
No $hit Sherlock! I've asked the question before and I'll ask it again even if you remain incapable of responding another time!
"Do you believe 74, 510 and 626 represent the same value? "
Maybe I need to ask the question again if you missed it.
"Do you believe 74, 510 and 626 represent the same value? "
Do try to wrap your head around this simple notion this time. Is it beyond your scope of awareness? Sheesh!
The reason you won't expect to hear much (if any) difference between two interconnect cables is not because the scheme is flawed..
That is just too funny! The idea behind a cable comparison is to.. well compare different cables (presumably by themselves)! When one forces each to share the combined characteristics of both, there is no longer a comparison - other than A+B vs A+B. What does any (intelligent) person expect? Apparently, present company excepted!
it's because there simply isn't that much difference the interconnect cables could contribute.
Opinion so noted. And contrary to my experience.
I realize the ship has sailed
I wish you the best of luck convincing anyone of your bizarre lack of understanding. :)
Me: Fail
Satie: Fail
Bob R: Fail

If not interested in learning, then obviously you're wasting your time. :)
You still can't get past the A+B vs A+B premise/comparison? My goodness.
The voltage source removes the "+" from that comparison. So, you do actually have an A OR B comparison even though connected to a common source. I'm not sure how much simpler I can explain it to your feeble brain. The voltage source becomes the buffer between the two (A or B) interconnect evaluations.
This really is BASIC electronic stuff. :) I've been working in the electronic instrumentation world for many years and this is bread and butter.
Dave.
I confess that I'm not surprised you remain incapable of answering simple questions. Multiple times.
This really is BASIC electronic stuff.
Second logic fallacy: appeal to authority
Obviously, with zero content to support it - because there is none.
I've been working in the electronic instrumentation world for many years and this is bread and butter.
Hopefully I never purchase any electronic device where the designer doesn't understand the difference between 74 and 626.
"I've just wired your new home! Don't mind that you'll find 74 volts at some outlets and 626 at others. It's because there simply isn't that much difference" :)
We're loving the humor!
Hang in there. One of these years this subject will illuminate for you and you'll think back and say......"Aha, that's what he was talking about."
Dave.
non-responses to simple questions. Sorry to go over your head with them. Clearly, no one is surprised with your lack of any content to support the farce.Aha, that's what he was talking about."
You're not only clueless but don't pay any attention to my previous comments. Interconnects have already made a substantial audible difference in my system. Is anyone home?
So, what hallucinatory drugs do you take to derive your point of view?
edit: I'm aware you make DSP crossovers for Siggy's speakers. That's enough for me to never consider them for purchase.
