Bought some 14/2 “speaker wire” from Home Depot

So I decided to amuse myself and on a recent trip to the Home Depot I bought some 14 gauge speaker wire. 25 ft for under $11.
I have what I think is a good system and my current speaker wires are analysis plus mesh oval 9 terminated in spades. My system is noted in my profile.
I substituted in the 14/2 I picked up- each leg is about 9.5 ft. Tinned bare wire at each end. I did use 4% silver solder.
Quite listenable, though perhaps not as extended at the high end. If someone told me I had to use the Home Depot wire I’d get along just fine. Leads me to one of 4 possible conclusions- 1- my hearing stinks; 2- my fancy Analysis Plus cables aren’t anything special; 3- my system isn’t resolving enough to make a difference; 4- given sufficient gauge, cable is cable. Of course, it’s also possible that my system is so good, any wire will allow that to shine through 
Your thoughts, comments, etc appreciated 

thanks
