Naim are certainly not the only manufactures to eschew the use of a Zobel network on the output of their amps - just off the top of my head there is NVA and Spectral. However, there is no network in the cable itself (at least not with Naim and NVA, you don't need a Zobel network as long as you aren't using high capacitance cables (and the cable presents sufficient inductance). Few speaker cables are high capacitance but there are exceptions (Goertz for example).
------
Regarding the audible difference between thick and thin speaker cables - I can't speak for Jez but I suspect his line is not that cables cannot make a difference but that as long as they are sufficiently specified they should not make a difference - the point being that the thin speaker cable is insufficiently specified.

Well, A/ you've effectively done that and B/ I don't know the detail of the Spectral and NVA but the essence of what I wrote is true.

Well.... it is, but whether it shows up discrepancies/inadequacies elsewhere is another matter and not it's fault.

Fair point. It could be that.

A/ Yep B/ Many amps these days don't use an inductor at the output... It was fairly de rigour and still is in power amps in general but amongst hi fi amps probably 40% or so these don't use an inductor at the output. Naim use 0.22R resistor, limiting damping factor to 18 for a 4R load, several others also use 0.22R, MF used 4 X 0.47R in parallel in many of their amps...
A Zobel network (AKA boucherot cell) is generally a good idea and is in parallel with the output rather than in line with it. Its reactance drops with frequency but at 20KHz would typically be equivalent to putting an extra 85R across the amp output. It's work is done at much higher frequencies. A feedback amplifier will usually have an inductive output impedance and it helps to counteract this and so aids stability in the amp itself (ie not oscillating!), as touched upon by Chris above.
