Rather than belaboring the point as to whether cables make a difference or not, let me just say that I believe
other factors dominate over cable or even DAC/amp selection.
--so, impressions talk it is here?
I have a wealthy audiophile friend, so actually I do get to use fancy cables and DACs and amps should the fancy take over me. I suppose I have at some point borrowed some megabuck cable of his at his place to connect my setups. I can't say I've ever noticed a difference that such a cable made on my setups when I was tuning them. Turning on/off corrective EQ tuning and/or HRTF processing always makes a night and day difference.
...and I know that cables make "a night and day difference" for most folks here too--let's just say, you try my
soundstage DSP mod and then come back and let's talk about what a night and day difference consists of?
