RCA cable can improve the sound? IMO yes!
1. If someone thing the cable didnt help or change the sq, what is he/his basis

2. Sound is combine of tones from 15Hz to something higher than 20Khz.
3. Electrical characstics of them vary from frequency to frequency : RLC (resitor, inductor, capacitor).

4. RCA cable has those RLC.

5.One more thing is AC current runs differently base on frequency. Higher freq will tend to run on surface, while a DC current will run all cross section.

6. So a big single core wire is not good compare to a combination of many tiny cores.

7. Atleast we have some reason to comfirm bad rca and good rca.

8. Money is other story.

1. Science and reality
2. You missed most of the audible spectrum which lies below 15kHz
3. Resistors do not vary their value significantly at all with frequency
4. Very little L, very little C, like under 20pf/ft, and very low R depending on wire size and length. The only possible interaction is C with a high driving impedance, and length over 20ft.
5. Skin effect only becomes an audio modifier when the total change in impedance it causes along with the load creates a variation in frequency response in the audio band. This doesn't happen with RCA interconnects because the wire size is too small relative that the total skin area, and the loads are very high impedance.

6. Depends on the load...see above.

7. Nope.

8. On that one I can agree.
