@cd318.
No one as far as I know in music or film claims that they can improve upon the original recording
Isn't this what MQA claims to do?
Though that subject is not to do with cables.
However rubbish components and speakers (or just one of these connected with an expensive cable) will effect the sound. I do not believe a statement that "expensive cables make a good difference" is correct. There are many factors that can be in place effecting a listener's hearing judgement. I am confused as to the OP's question, or intention. Are you asking whether we, the readers or those also posting back, endorse the three cables you have enjoyed in your listening session? And therefore agree that these are well matched to a 35k system? And somehow, if we haven't heard them, we need our ears checked? Or our wallets cleaned out?
You can make a photo or movie appear 'better' by photoshopping it or re-digitising a movie such as the original Star Wars. But the original data stays the original data. And enhancing it such as the above does make a better product, but does it meet the original creators intention?
Indeed, cables may influence the sound of reproduction to the final end, the speaker, but is that sound the intention of the creator (artist, sound engineer or post production technician?
Are you happy distorting the eventual sound or want to hear the sound as closely reproduced to the original? Are you happy with MQA as this is claimed by many digital listeners to be superior in sound?
Sepia photos have a ageless quality about them. They are not the same photoshopped, except to correct the omissions in the original image. I expect that original recordings on vinyl are the same, closely matched to the original intent of the music, which is why they command a premium price over re-engineered pressings.
Cables are designed to transmit relevant electrical data from source to end point. If there is interference in the middle, cartridge pickup to speaker driver, then expensive cable may amplify errors, or make no difference to the ultimate sound reached by each individuals ears.
To finish with a question, "What are your thoughts?" invites a full appraisal of the OP's post. These are my thoughts. They do not invite response.
