To Summarize: Sounds like the OP pulled a few spare bits of DNM cable out of his toolbox and made an improvement to the sound of his system at no cost and without the need for committees to be formed for reviewing the results of extensive double-blind tests (which need to be DBT'd themselves of course), ad naseum.
Ultimately, the OP simply reacted like a normal person who experienced a positive change and shared it with (some) other (normal) folks in a hifi forum hoping it benefits fellow forum members.
Note for the normal folks here: pardon my overly, complex summary but...you understand.
