OP,
YMMV....
I was in the same dilemma about 2 months ago. i I was using Transparent Music wave and was short of about 2 feet..( was in the process of rearranging the system layout) so I decided out of fun, to add a zip cord BUT terminating it correctly and NOT messing with the Terminals of the Transparent cable. Yeah, it sounded GOOD and I thought, Heck it works
BUT my curiosity told me to test it without the zip cord, so i had to pull the speaker wires outside (trip hazard) and remove the zip cord. Oh no, there was a loss of dimensionality of speakers. ( my speakers are Falcon Gold badge known for 3D presentations)
To cut it short, I ended changing my cables to longer Ultra Transparent
Threw my budget off big time
