For my amplifier - LAvardin IT - both types of DNM cables work very well - in fact I use and have some Nordost Heimdall 2's and I found that the DNM's gave a better sound with better flow and cogency.
I spoke to LAvardin on the premise I required cables longer than they manufactured and they recommended the cheapest Nordost cables - called 2 FLAT - they told me to save my money and not waste them on more expensive cables.
I came across some cables by a company called 'wire on wire' and in the set-up I heard them in they were good and very affordable.
There is another cable that I have used by a company called 'Missing Link' in the UK as well
