Adding an extra 1ft to premium speaker cables

@roadcykler - "Electricity doesn't know nor care if it's OFC or silver or any other conductor if it's the same or similar gauge wire."  So electricity doesn't care about the composition of the medium through which its propagating?  Unless you are making an existential point about electricity not having separate consciousness, this is complete nonsense.  

the cables can be expensive, there's no charge for the expectation bias.

Here are a few points to consider: if one adheres to the theory of allocating 20% of the speaker’s cost to speaker cables, there is a higher likelihood of aligning the quality of wire used within the speaker. However, it is important to note that changing the wire inside the speaker to a higher-quality wire does not necessarily guarantee a superior sound quality. It is possible that the speaker’s voice was intentionally crafted to resonate with specific wires.  

OP made his point in a questionable way, but it's a fair point nonetheless. 

The problem with most armchair Audiophiles perorating endlessly in forums about the stunning aural benefits of tweaks, network gear and cryogenically treated USB cables is that they can't tell the difference between a soldering station and a train station and they've never even taken the covers off their gear. As a result, they have no idea what lurks inside. How about $4000 power cords going into $500 wall receptacles, themselves screwed onto decidedly non-Audiophile Romex held together by garbage wire nuts? Wire nuts! Talk about microphonics now. And how about $400 graphene fuses snapped into 10-cent fuse holders made of common steel? Etc

Meanwhile, everyone politely agrees to ooh and aah over the emperor's new clothes, including genuine audiophiles who know better.
