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

I have found that most speaker wire in most systems barely moves the sonic needle.  The only speaker cable that made a meaningful difference in my system is Auditorium23.  My 16-yr old daughter listened to them and said "they sound more detailed than your old wires".  She was spot on and she has never even been exposed to audio jargon.
@11.00 for 25 feet it is an alu/copper clad?. If it was pure copper in zip cord, that would have helped.  Copper works very well, but don't tin the ends, that will change the sound to.. 4% silver and 96% lead and tin...
99.99% copper, and a graphene paint.. Mind blowing, simple, but great results...50 hours to settle...

It would be pure copper as pretty much all residential 14 awg Romex is. How will tinning the ends change the sound? 96% may have lead may not.
I tinned the ends to prevent any stray strands. The wire I bought is all copper- not copper clad aluminum. 
And Ms. Boyd is always happy - which is the most important thing 
Re dedicated line- i did that in my prior home and it was without a doubt the single biggest improvement, dollar for dollar, that I ever made. Did a home run to the panel with 10 gauge. Electrician thought I was nuts when I asked for 10 gauge.
