Can interconnect cables improve sound stage height, width, and depth?

Lamaze, I suggest you leave the jokes to someone else. 

Subjective impressions are the equivalent of "a little birdy told me it is so)!!!

Roberjerman try to audition Teo Cables , Cerious Tech Cables, Nordost at least heimdall level , high fidelity, Dana Cables, Audioquest mid price, Kimber midprice, and more...you will be the judge see what you will hear....please let them settle...

@blamere, sometimes yes, I’ve found it to be system dependent.
I think people that say no are opinionated and/or have not tried experimentation.
One should be able to hear a difference with good components and a trained ear.

Brands offer different levels of build, and cables, components, speakers, tweaks treatments and rhevroom will contribute in your overall sound.  

With that being said, I recently swapped a reference line XLR from my DAC to Preamp (which yielded great results) to now from the PreAmp to the Monos and gained even greater results. I will circle back at some point and upgrade the XLR between the DAC and Preamp.

Could this have been done with less expensive but still well built cables, possibly, but that was not an option. 

As as many say let your ears and wallet decide what’s best for you and never forget to Enjoy YOUR Sound!
