Is high or low capacitance better?

The higher the frequency, the greater the reactance caused by the capacitance and the greater the signal loss. In the music world, a lower cable capacitance provides a “richer” sound quality. There is more of the natural “brightness,” “presence,” or “bite” from the instrument that can reach the amplifier.

How is RCA cable capacitance measured?

Remove the cart, then clip one probe of the meter to the outer shield of the rca, and the other to the center pin. Before you do this record any reading on the meter as this is the capacitance of the meter cables (some meters you can zero).

What is low capacitance phono cable?

A phono cable is made for impedances from 10 ohms and under 0,2 millivolt! This phono cable has to have a very low capacitance (under 80 pF by meter) and low resistance. A phono cable serves to connect the tonearm of a turntable to a phono preamp. This is the case in most Hi-Fi set-ups with a vinyl system.

What makes a good interconnect?

The longer it is, the higher the capacitance. This is why interconnect length should generally be minimized. Capacitance is minimized by spacing the two conductors apart as much as possible and by avoiding parallelism. It is also minimized by using low dielectric-constant materials between the two conductors.

When to use low or high capacitance cables?

Higher cable capacitance will make the load values on either end more critical to proper matching. This is why folks recommend as low a capacitance as possible with long cable runs. I find that the cables I’ve tried with high capacitance usually sound warm, bloated and slow.

What is the capacitance of an RCA cable?

The capacitance of that cable wired for standard single ended audio (and even for balanced audio) is going to be way, way higher than 3.4 pF/ft, if I’m ready the specs correctly, more like 23 pF/ft, but I don’t think that’s even the spec if you connect the shield to the return in for use with RCA. I think the cap will even be higher still.

Where can I get a low capacitance phono cable?

Grover Huffman cables found at home – www.groverhuffman.com have a new line of very low capacitance phono cables and low capacitance interconnect RCA cables. He was able to cut capacitance in half in 2017. The difference in the interconnect cables was very significant from his previous line.

What is the response of a low Capacitance Interconnect?

Simple math shows that interconnects with reasonably low capacitance won’t affect system response enough to matter. Specifically, with a source impedance of 1000 ohms, high for all but passive preamps, infinite load impedance, and a typical 200 pF interconnect, the response would be 3 dB down at 795 kHz.
