I have never seen a 600 Ohm cable. The old TV twin-lead was 300 Ohm. A 600 Ohm cable would be a widely spaced pair.
Wait a minute! There just might be a 600 Ohm speaker cable. I think that the brand name starts with "S".
I dimly recall some ladder line used in an old ham radio setup being 600 ohm. But that memory is 50 years old, so...😀
If the cable really has a characteristic impedance of 600ohms, do the terminations also have 600ohms impedance?
Not at all, of course 🙂
This is a kind of "diminishing return" that I am personally satisfied with.
And yes, in order to cut the comments of other members - this is strictly placebo effect since I am not able to measure it or at least do a proper "A/B" blind testing.
I am fooled by an increased distortion and therefore I think it is a better cable although it is actually worse.
I do not dare to say it is more "transparent", "detailed", "dynamic", "wife in the kitchen" or so since these are just foolish words not contributing to anything.
You have been warned.
This is exactly how I feel. If I say I prefer cable A to cable B, that is OK. But is I comment I hear better resolution or extended highs or lows, the Tall Ones come at my throat with pincers.
That will do you no good. There’s only one true measure of success, and that’s how close you can get to deciphering the Mayan hieroglyph.
Cable capacitance (plus load capacitance, which often dominates) forms a low pass filter with the output resistance of the source. Hence excessiviely high capacitance should be avoided. Once the cable capacitance is sufficiently low there is no advantage in making it any lower. So the rule is not 'low capacitance cables are better' but 'excessively high capacitance cables may be worse'.merlin el mago said:
Real 600 ohm cable comes in two forms:Speedskater said:
1. RF 600 ohm cable - this will be widely spaced twin line used as an antenna feeder and/or matching network.
2. Audio 600 ohm cable - this will be a closely spaced twisted pair with 88mH(?) inductors inserted every ? km, as used in telephone trunk cables.
Modern audio does not use 600ohm cable. It may use twisted pair cable between 600 ohm sources and loads, but the cable won't be 600 ohm.
If only you meant all that - it would be a sign that you are starting to learn about audio electronics.Baka said:
That is OK. You can express a preference between two identical outcomes, or even prefer slightly degraded sound.WntrMute2 said:
To believe that we need data. As SY has said, data is not the plural of anecdote.
The reason why we need data is that the claim is overwhelmingly improbable. Those with a weak grasp of circuits may not understand just how improbable, hence they are surprised or feel offended that we doubt their perceptions. It is almost like someone saying that he really did find fairies at the bottom of his garden; he should not be surprised or offended if people ask for evidence.
1, 2 and 3 are just standard bulk cables, 4 and 5 I have no idea.
However 1 and 3 are meant for 75Ω connections while 3 is a star-quad microphone cable.
Star-quad is designed for very specific conditions when even normal balanced XLR cables do not give enough RFI immunity by using 4 internal conductors rather than just two. This of course doubles capacitance and star-quad is only really needed if you build a recording studio next door to a radio transmitter.
