Let me rephrase my question, does a two wire interconnect have better frequency response than an interconnect with a four wire configuration, all else bring equal?
9 responses Add your response
If you are using a two and four conductor cable of the same grade from the same manufacturer - frequency response should be the same.
However, connecting the four conductor cable in two pairs will double the capacitance - this can effect the overall tonal effect the cable has on the sound
Connecting your tone arm wire in this manner could have significant effect on the sound, since capacitance is one of the variables often taken into account when matching a cartridge to the phono stage. From the specifications of cartridge and phono stage, it may appear to be a good match, but because of the capacitance of the cable they may not sound as expected.
Capacitance Is often overlooked in audio matching - e.g. Naim amps do not perform their best if used with a high capacitance speaker cable - and they used to state that on their website.
I've often read posts that report some interconnects sound bright or harsh - but it may not be the interconnect, but the combination of that interconnect with the attached component.
I now ensure all my cables are low capacitance to get the best neutral sound possible
So beware of capacitance
Actually I am being very attentive about the capacitance , as I understand the Impact that this can have on higher output cartridges. So I have been selecting cables for low capacitance.
At first review of the specs it looked to me like the 2534(4 wire) had lower capacitance than the 2549 (2 wire) cable. But going back to the spec after reading your post I noticed that the spec lists a capacitance for "balanced quad connection" and that figure is more than double.
So this to me this is clear.
Where I am not clear is the frequency response graphs shown in the Canare paper linked in my OP. The graphs show the four wire variants having better frequency response their two wire equivalents. See figure
42 & 44 on page 10. Am I misinterpreting the graph or is there an error?
Mesch - I have the Cardas one-piece tonearm wire that I find very good for phono but I don't know the Capacitance
For Interconnects I use the Van den Hul D-102 mkIII as a becnhmark which is rated at 37pF/meter
For speaker wire anything below 30pF suites MY AMP
NAIM actually states on their web site...
- 1.3 - 1.5microHenries per metre (Loop)
- MAX 20picoFarads per metre
- About 25 milliOhms per meter (loop)
- MIN Length 3.5 metres
I use "low capactance" as a guideline, in that too much capacitance in cables may effect the sound
I don't think I would state that all cables should be low capacitance across the board for everyone :-)
For phono it seems to be the case, BUT it REALLY DOES DEPEND on the components you are connecting
In general I agree with your statements regarding low capacitance, however the numbers you quote appear to me as very low, are you sure that they are not pF/ft and not meters? I checked the Van den Hul site and they list the d102 as having a capacitance of 61.5 pF/m core to core, which to me seems more inline.
With a combination of Cardas 33awg litz inside the tonearm and the Mogami w2549 Interconnect I am estimating between 100 to 125 pF total. This is arrived at by adding the core to core and core to shield capacitances. Note that VdH only lists the core to core figure.
125pF should be more than sufficient for my current HOMC cartridge and for almost any other cartridge I decide to use in the future.
