Hi Ali,
Indeed. I'm not at all surprised that Mark's cable measures as flat as a witches tit.
However, aside from that, any adverse sonic effect, however slight, you heard with the G1000HDs, I would suggest is not as a result of the characteristics of cable itself, but rather of the Canare plugs supplied. I should've made that clearer in my post on your ad. I will amend it shortly.
I can say this because I've heard exactly what you describe, and it is completely absent in the G2000HDs, or the cables supplied with Neutrik Pro-fi plugs.
The Canare plugs are of good quality (and Mark could hardly fit any better on his already great value for money entry-level cable), and are well constructed, but they do contain a large amount of metal, which a number of us have discovered recently is, sonically, a no-no.
It's to do with metal storing eddy currents. There are papers about this on the web, should you wish to read them.
This effect was discovered recently when comparing WBT 0102cu plugs (which contain metal in their internal construction) and WBT 0110cu plugs (which contain no metal, other than on the necessary conductors).
The 0102s are slightly more expensive, due only to the metal contained in their construction, yet when used in conjunction with Mark's excellent G1000HD cable, the sound is notably worse than with the 0110s...... Basically, the top-end is curtailed, and so the sound is somewhat 'softened'.
You can clearly hear the effect in a high quality, neutral-sounding system.
As for the Neutrik Pro-fi plugs, I can't recall their internal construction, but I suspect that overall there will be less metal used than on the Canares. Plus also, their design is better, in terms of how contact is made, in any case.
Therefore, what I'm saying is not necessary to attribute what you've heard as being an effect of the G1000HD interconnects as a whole, but rather of the Canare plugs used.
It's something that I'd ask others and you to consider. It's long been my belief that the sonic effect of cables in a hi-fi system is more often than not as a result of the plugs used than the wire.
To that end, Mark should perhaps consider making his G1000HDs come supplied as standard with Neutrik Pro-fis (as priced on his site) and consider dropping the Canares. I'm sure that most people willing to spend £65 on interconnects would spend £90 on the same ones with much better plugs, and consequently significantly improved sonic performance.
This would then improve the quality of Mark's best selling entry-level cable - and the overall reputation of his products accordingly.
I'd be interested to hear what Mark's thoughts are on this?
Marco.
