AQ vs Van Den Hul

Well said @boxer12.  AQ cables are generally very neutral.  As you move up the line the sound gains transparency and openness, bass power and dynamics.  Sorry, I have no experience with VDH.

The Van Den Hul  First Ultimate is one of those wild exotic design -- apparently it doesn't use metal and uses some sort of carbon threads to conduct.  I can't even begin to predict what it would sound like.  You really need somebody who has personal experience with this one.

Thanks guys. I plan to buy B&W 702s2 soon to pair with some older Rotel gear and know B&W always uses Audioquest to demonstrate their speakers at shows; however, I was told B&W uses Van Den Hul for internal wiring in their speakers (at least for the 800 series) which sparked my interest in the VDH line of cables which I wasn't very familiar with at all.

@mkash3 ,
You can always call AQ and ask them for their opinion. 
Heck, even call VDH and see if they sell B&W their cables.

I used the VdH First Ultimate for many years. It seems like almost 20 years ago that I bought my first pair. Maybe not that long..? It’s made completely from carbon fibre except for the terminations. The terminations are not soldered to the carbon fibres, so if the termination becomes faulty, it has to be sent back to the factory for repair. The termination pins are split, so there is potential for the terminations to become damaged. They sound great, perhaps a little soft, and they lose some dB compared to copper or silver cables. That was always the two downsides with the First, Second and Third cables (all of which I have owned). I would place their performance as better than the VdH copper interconnects, but not quite as good as their expensive pure silver models. The top end and midrange are superlative and definitely not strident, but the bass lacks the last word in dynamic punch compared to MC silver models.
