Interconnects and non-believers

For anyone who denies there are differences in cables, I have news for you.
There are vast differences.  I just switched interconnects between my CD transport (Cyrus) and DAC (Schiit Gumby), and the result was transformational.  Every possible parameter was improved: better definition, better soundstaging,  better bass, better depth etc.
I can’t understand how any audiophile with ears can deny the differences.  Is it delusion or dogma?
