As one spends more on cables they are far less likely to be one size fits all - so to speak. For instance Naim and LAvardin can't use goertz style cables due to high capacitance although they love DNM cables - so however much one spends and tries using a high capacitance cable it is not going to be an improvement on the cheaper DNM. So, as you spend more there may well be system matching issues - indeed the more you spend may result in worse sound.
All said and done, despite some companies saying otherwise such as Nordost (I have some of their cables BTW) cables are 'tone controls' IMHO some allowing more details than others, with various other tonal differences as well.
