Bass leaves after amp warms up?

I substituted Different high end speaker cables today.
What I heard was alot of bass but it wasn't the lower octive & punchy kind which I get from Audioquest.
Is it possible audioquest cables can in the first hour put out a more desirable bass like a subwoofer that is punchy but then "resort" to bass that is less deep or punchy?
Which is unsatisfying to me

Perhaps I need a subwoofer?

But this is perculular:
I put back Audioquest cables using just one speaker & was unable to get the "correct" bass from either side of the amp.
I then tried the other speaker cable from audioquest & the bass was powerful & deep again.
So I don't know what this means

No, IMO.

My guess is that something else was changing (perhaps as a result of cooling off somewhat) while you were changing cables. Although you'll want to determine if the different behaviors with the two different cables are repeatable, to cover the possibility that one of the two cables is defective in some manner.

Either or both cables work well at any given time:
There is no pattern

When the electrician comes also confirm continuity with his volt meter red to red and black to black at both speaker wire ends .....
Also when you hook the AQs back up make sure the bass goes to the low speaker posts and tweeter goes to the high posts .
This will make sure your speakers are in proper phase.
You can also disconnect both speaker wires at the amp take a double a battery red to batteries plus black to neg and run it on both speaker wires if both speakers woofers are moving in the same direction all is good.

Agree with Newbee on using an SPL meter and LF test tones to gather data.
