Overall a worthwhile listen, I wasn't giving it full attention so ...
Yes, like you, I had to take a second listen to actually digest the content of the discussion.
Most of the myths listed were busted a long time ago but still seem to be tightly held on to by a few diehard audiophiles. I do like the comment abouts Super tweeters and magically hearing above 20Hz when what you are actually hearing is "Sub" harmonic content from HF distortion. I also like what he said about marketing B.S. Marketing departments have no regard for correct engineering terminology and will often completely misrepresent basic engineering principals in order to make a product look desirable. This situation is already prevalent in audio as HiFi marketing material often makes claims about audio product that seem to operate outside the laws of physics.
I also agree with the comment about mastering being the critical mechanism that is causing the differences when considering the Analogue Vs Digital debate. In my own experience it's a 50/50 split, when I do comparisons between albums I have duplicated on LP and CD, sometimes the LP is better, sometimes the CD is better. The most critical component is the original mastering, not the delivery format.
I do like what is discussed about speaker cables, the opening argument is that they are an avenue for tweakery rather than having any real merit in most situations. In most cases the effect is greatly overstated. It does make sense what is said about needing thicker cables today because of modern speaker impedances becoming lower where 4 ohm is the new normal rather than a more traditional 8 ohm. The main metric is about increasing the cross-sectional area, not using exotic materials, on this I can only agree. I also agree with him on exceedingly high capacitance speaker cables. Hi capacitance cables don't actually improve detail; they introduce a brightness to the sound by driving the amplifier into instability and "pre"-oscillation, this situation can be demonstrated on many different amplifiers, not just Naim.
I was interested in his closing comments about speakers, the BBC dip which is a deliberate trough in the midrange region to counter near field monitoring aberrations and Darko's comments on the reluctance of audiophiles to fully embrace active studio monitors for accurate sound reproduction. To my mind he mostly corroborated what I had already felt to be about right, although he did get a bit "flowery" in some topics, I tend to turn off when engineers start talking too subjectively.
I actually like a lot of Darko's content and have been following him for a while, he doesn't do silly voodoo (except on April fool's day) and admits that he uses AudioQuest cables because they one of his sponsors. He doesn't openly push cables or even review cables. He also says in relation to accessories, that you need to make your own decisions based on your own needs and budget.
