Baroque lover, like you I am very sceptical about a lot of cable pricing in terms of value for money. I can understand why some cables might cost more. They may be hand made in small batches. Ot they may use exotic/expensive materials. However, for most cables this is not the case. Any audio retailer will tell you that cables are high margin items. That's why the big box stores push them so much, to add some profit to the low margin TV or CD player they are selling.
As to the value of the cable in improving the system. I think a distinction has to be made between a cable making a "difference" and a cable producing an "improvement". A difference is not necessarily an improvement. I think many cables produce differences, but not always improvements. Certainly, many people will swear up and down that a certain cable imnproved their system. I think this can be true. A cable can compensate and mate with what it is attached to in the same way that a component can mate well, or not so well, with another component. But I would expect cable improvements to be more subtle since there are fewer variables to work with when changing a cable as opposed to an entire component.
And if you do a good job inside like Totem, there is little to compensate for with an extenal cable, which was the point I was suggesting in my original comment. In this circumstance, cable changes are more likely to produce "differences", but not "improvements". Or if it is an "improvement", it is an improvement in terms of the person's personal taste, and not in an absolute sense.
I am always surprised that one of my favourite manufacturers, who make some extrememly expensive stuff, don't seem to give much of a rat's tail about cables. All they recommend is a good quality 4 mm multi stranded copper cable. They don't seem to have any regard for all of the exotic material and construction (and marketing) that's behind a lot of expensive cables.
I'm not wealthy enough to experiment with a lot of cable changes anyways. So if my thought are wrong, I remain happy in my ignorance. I feel no need to change anything.
As for connectors, they seem to be a necessary evil, like cables, unless you have all of your components hard wired together. I don't think bare wires by themselves produce a strong enough conenction.
