@johnson0134 - I really late to this party, but found your post to be interesting.
1. The price was NOT indicative of the sound quality unless you go very cheap (less than $100). I think this point is self-explanatory so I am not adding any elaboration.
Comment: This makes total sense to me as the price of any product should based on the materials used and time spend to produce it along with the market value for the item. Using more expensive materials and more complex construction doesn't in any guarantee and better cable. I would expect that a more expensive cable within the same brand should be better for any reputable company that isn't just selling snake oil. Also, some companies like Blue Jeans Cable have a business model that's based on value rather than appearing to be a boutique brand, so it's possible that their products can be a much better value.
2. Disconnecting and re-connecting the cables had a very positive impact on sound quality, which will affect any AB comparison. If you are comparing two pairs of cables that had comparable sound quality, the new cables will sound better because the connection would be fresh.
Comment: If true, it's easy enough to disconnect and reconnect a cable when doing comparisons. It seems like this would lead people to prefer the new cable over the old one, so I'm curious how often people try a new cable and immediately do not prefer it.
3. In my experience, the cables were NOT system dependent. This might raise some eye brows as it goes against the commonly held belief so I am going to explain a bit here
Comment: I think that cables can be system dependent, but I think listener preference is likely a much more significant factor. The science of cables is hard to nail down, but the fact remains that whatever a given cable does it'll always do, so if the listener likes the resulting sound it's expect that they will continue to like it. The system dependent aspect comes when the rest of a system is already too far in the direction that the cable brings out and it's always possible to have too much of a good thing. When it comes to cables being in different parts of the audio chain, it's an apples to oranges comparison. From what I know about gain structure in pro audio applications, it makes sense that you'd want the best cables closer to the source as any noise/distortion will be a more significant portion of the total signal that will later be amplified. In a very general sense, this is why phono cables are much more finicky than speaker cables.
