@PerF - that's strange, because it is so different from what I hear. Perhaps this just reinforces the point that every room, speaker and ear is different, so trial at home is important when spending that sort of money.
@justin65 - Fair enough - there are certainly plenty of smoke-and-mirrors salesmen in the world of cables, and my understanding is that Naim's original stance on cables came directly from Julian Vereker's view that cables make no difference (except those few that are not designed properly).
The fact that so many people who have heard non-Naim cables and moved away from Naim cables afterwards may have contributed to the existence now of Naim's Hi-Line and Super Lumina interconnects and SL speaker cables - Naim may have reassessed the whole issue and reached different conclusions. Mind you, some cynics will argue that Naim saw what was being charged for flash cables and could't resist.
In any event, Naim would now be delighted to sell you different and much more expensive cables, so the Naim of 2022 certainly thinks that the Naim of 2002 did not have the 'right' answer here.
Personally, I am happy to listen and decide, without loyalty. After all, Linn firmly believes that LP12s should feed Linn amplification and Linn speakers, via Linn cables. Given my tastes, system, room and ears, I am absolutely certain that would be wrong for me, but that does not mean Linn staff are deaf, incompetent or dishonest. It also does not stop me being very happy with my turntable.
