No.Hi,
is there noticeable quality difference if the balanced audio signal is transfered through an 1m cable or a 2m cable?
It is very hard to say, since price is not always reflective of performance. So you can have a 50E cable performing better than a 500E one, depends on the cable, and partly the impedance of your headphones and/or the output impedance of your amp. But, If you think an expensive cable is going to transform your headphones, then I am sorry, it won't. Save your money for better headphones or amp. As long as your cable is not faulty, that is all you need.What do you think is the reasonable price of an upgraded hp cable for a hp of 400 Euro? 50 Euro? 100 Euro?
Some cables have tin foil. What advantages does it bring?
Although generally true, but for a headphone cable, the noise issue is irrelevant.One of the major points of balanced connections is that they reject noise and can be used for long cable runs
Those are for input cables, not output cables. You are replying to a headphone cable thread.In fact the main virtue of XLR balanced interconnects over RCA unbalanced interconnects, is in long runs.
Not much difference in 3 meter (10 foot) and under interconnects.
There is a certain minimum price for making a 'balanced' cable from a materials and labour standpoint. But spending more money will not get you any amount of better sound quality. You might want better connectors (Neutrik for example) for reliability, or a nicer sleeve or even braid to make the cable look and/or feel nicer. But where having a 'balanced' connector like XLR can give you more power and therefore potentially higher sound quality, nothing (reasonable) will affect sound quality.What do you think is the reasonable price of an upgraded hp cable for a hp of 400 Euro? 50 Euro? 100 Euro?

In a portable amp, running on batteries , peak voltage available is limited.Yeah, there's absolutely no point.
In almost all cases the only reason to use a balanced headphone cable is to show others that you spent a lot of money on your system ...
2 Times theYeah, there's absolutely no point in using a 'balanced' (actually differential) cable for your headphones these days. Differential cables allow the amp to generate more power by using twice the amplifiers in opposite polarity,
4 times the power (2 times voltage swing).2 Times the power but only ~1,4 times the noise.
Yes right.4 times the power (2 times voltage swing).
No. that's the beauty of it.2 times the noise voltage.
I said noise VOLTAGE!Yes right.
No. that's the beauty of it.
To incoherent noise sources of the same strength add toso approximately 1.4
i know but its not 2 times the voltage.I said noise VOLTAGE!
Please explain that, why is it root of this and that.i know but its not 2 times the voltage.
its ~1.4 times.
√ (1² + 1²) = 1,414...
Noise is per definition random.
if you add tow random numbers/voltages between -1 and 1 you don't get 2 you get approximately 1.4
No, he' is correct. Uncorrelated noise (or any uncorrelated signals) add by 3dB, as he indicates. If they are correlated they add by 6dB.Please explain that, why is it root of this and that.
In balanced mode, we have two amplifiers, with two noise floors adding to each other.
In voltage, the noises just add up. so if one amp has a noise floor of 0.1mV, then two amps will have noise floor of 0.2mV.
You don't agree?
No this is not how it works.In voltage, the noises just add up. so if one amp has a noise floor of 0.1mV (peak to peak), then two amps will have noise floor of 0.2mV.
You don't agree?
Thank you, you are correct.No this is not how it works.
You can absolutely not just add this like some DC battery's in series
The Noise has polarity (or "phases")
So some of the noise is maybe adding but but everything out of polarity is subtracting ("canceling out")
"peak to peak" especially without bandwidth is btw. invalid if you talk about noise.
