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

Some years back, I had decided to replace my Silver Audio Hyacinths, and gotten a pair of Wireworld’s Platinum Eclipse interconnects. With the Hyacinths, I was enjoying a wall to wall sound stage(with attendant, accurate, imaging) and excellent/realistic height and depth(with recordings made in open venues, that contained the ambient info). Installing the Eclipses, while realizing more air, greater inner detail and tone quality, the sound stage was reduced to between the outer edges of my Magnepans. I then auditioned a pair of Synergistic’s Tesla Apex, which yielded EXACTLY the same benefits/audible improvements, as the Eclipses, but- restored my sound stage width. They’re still in my system. Besides using my own recordings for sound stage verification, I like the tests(especially the LEDR) on the Chesky CD: http://mazsola.iit.uni-miskolc.hu/~drdani/cdlist/chesky.test1.html and https://www.audiocheck.net/audiotests_ledr.php Prior to that experience, I had replaced a pair of Audioquest Emeralds with the Hyacinths, which was tantamount to removing a blanket from over the speakers. YEAH- interconnects make a difference!   https://www.stereophile.com/features/772/index.html

Oft times simply reversing the interconnects results in better sound. Talk about a free tweak. A real no brainer. 🧠

"Wire may be wire," but the design and implementation of a cable does affect it’s sonic presentation. I have found it has to to due with the metallurgy and how it’s implemented by the designer.
Look at all the different conductors and dielectrics used in IC’s and other cables. Conductors may be copper, silver, gold or any combination, they may be stranded or solid. And then there’s the metallurgy and design of the connector.

An IC doesn’t have to be super expensive to be a good performer. Grover Huffman makes excellent affordable cables that are transparent, organic, with wide and deep soundstaging.
At a higher price point Siltech cables offer realistic inner detail and an image that is focused and extends in all directions. Purist Audio Design offers different lines of cables, each having it’s own signature, but all offering an excellent soundstage. Silent Source offers a sense of realism and the reproduction of the soundstage as it was originally recorded.
The Cardas Golden cables, IMO, have a closed-in soundstage, while the Clear line of IC's present realistic height, width and depth.

A budget cable such as Belden produces a very good soundstage in terms of height, width, and depth, but lacks the nuances and organic characteristics the above cables provide. My 2 cents.

Every set of cables I own introduce different characteristics of the music, but compared to basic cables, you hear more. Those who say no differences, are either deaf, do not have a high resolution system, nor have tried any. Them the facts !

Yes! to your queries. System synergy is key. Certain brands of gear will fare better w/ their voiced cabling. Sometimes, we get lucky per mixing and matching different brands of cables/cords. A fun experiment indeed.
Happy Listening!
