Some thoughts about tonearm wire

I did not say a length of wire does not have inductance (or capacitance).  I did say that the gauge of the wire has little effect on reactance (thinking of a single conductor in space with nothing around it), compared to the geometry of the wire in relation to other conductors that might be carrying either ground return or the opposite phase of a balanced connection, in an IC or inside a tonearm wand, where you have two hots and two grounds running close together in the case of an SE circuit or two positive and two negative phases, if the cartridge is running balanced mode.  Twisting increases C, and running them side by side might increase L. Also, the wires inside a chassis can affect each other’s reactance depending upon how they are routed with respect to one another. The effect of those factors on capacitance would outweigh the difference in capacitance between two very thin wires of slightly different gauge singly in free space, or at least I think so.  If you have some data, I would be interested to investigate this further.  

Most of us by and large do not have access to your lab equipment.  Therefore, when you say that resistance should be less than 80 milliohms (I think that is an accurate paraphrase, but if not, please correct me), that is not a useful criterion for the rest of us who cannot measure down past, really 0.2 ohms.  I have expensive Fluke digital and Triplett analog meters, and neither can go that low. My Fluke meter reads 0.2 ohms when the two leads are in contact.  Furthermore, the slightest bit of dirt, grease, or whatever on the probe would screw up the reading of 80 mohms.  I also did not mention it before, but why or how did you settle on 80mohms as the max permissible resistance?  Just wondering. I have thought on this issue myself, once in a while. Many gain stages use a resistance in series with the grid of the gain tube or the gate of a transistor, in order to suppress oscillation of the circuit.  In a tube stage, the value of such a resistor is usually at least 100 ohms. I wonder how the resistance of the wire carrying the signal to one end of the "grid stop" resistor could make much difference in light of that fact.  I am agnostic, unsure what to think about that.

Forgot to mention that if you think your tonearm wire is thinner than 33G, based on direct inspection, I stand corrected.  Must have been a bear to solder that stuff.

@jc4659 I have experienced works undertaken on the Mechanical Interfaces and as time went on diverted the focus onto the electrical side of the same TA.

After a selection of designs and wire types tried. 

A certain wire used continuous really shone through for the attraction brought with it. 

It also left the impression the work undertaken on the mechanical interfaces were now really able to show off the quality they had created. 

I fully understand your reaction to your own experience. 

Femo's of such designs wins advocates fast. 

@lewm Actually, the 0.080 Ohms is not my criterion, it was posted earlier in this thread by westcoastaudiophile.  I don't know how s/he came up with that or if it was published somewhere.  Either way, if a tonearm wire resistance is that low, it would be hard to beat for a MC setup.  Given there are multiple contacts in the chain and round trip to the preamp and back, I suspect it is more than 80 milliohms.  When I get the tonearm back from service, I will try to measure the resistance of that tiny wire.

I suspect, but have no way to prove it, that one continuous length of wire with no contacts, just soldered connections from cartridge pins to preamp input, the sound quality will be dominated by this rather than the type of wire in the conductor.  

"Twisting increases C, and running them side by side might increase L"  Actually, twisting decreases L, not increases it.  The reason is the same for side by side wiring, current in one direction induces a current in the adjacent conductor in the opposite direction.  But since this is the direction the current is flowing in the adjacent conductor, inductance decreases.  As the wires move apart, inductance then increases while capacitance decreases.  In this case, resistance remains constant.  Increasing the gauge of the wire changes everything, but the basic rules remain the same.  

Spatial, please reread your own 3rd paragraph. You accurately quoted me then completely reversed the sense of what I wrote. We don’t disagree. As to discrediting you with the bit about 80 milliohms, sorry for that. I wonder how west coast came up with such a precise cutoff.  And how he measures it.
My own experience with running phono wires from cartridge to phono with no intervening connectors suggests it makes a big difference with LOMC cartridges, for the better.

"And how he measures it.” easy, using four point probing and nice Keithley 2016-P tester, here is description of principles: https://en.wikipedia.org/wiki/Four-terminal_sensing 

0.08 Ohm is critical for MC carts, in my case for using 4 Ohm and below output impedance carts. yes, there is a round trip for signal in each channel, which increases total tonearm only portion of resistance to 0.16 Ohm. combined with arm-to-SUT/pre-cable, that resistance increases easily to 0.2..0.3 Ohms level, which is significant relatively to MC output Z, thus such “small value" does affect SQ. typically tonearm wires resistance is lesser issue than contacts, if wires are not oxidized etc. silver/gold plated contacts can be damaged, and need to be inspected under microscope for plating surface integrity.
