Thanks, yeah I've been reading up on speaker cable theory to try and better understand why I am hearing such a difference...
Hi tranq.
To understand why you are hearing such a difference in cables, I suggest that you broaden your research to include psychoacoustics, how humans hear and analyze sound. There are qutie a few threads on ASR that should make your perceptions easier to understand.
Here is a really good place to start.
If you watch the 1st 6 minutes of the video it covers most of the ground. The full video is worth seeing, but the ASR thread it is attached to is also highly relevant and funny I think. It begins with a probably apocryphal story that purports to prove objectivists (like most of us here) have terrible hearing, but actually proves that everyone, including objectivists, is impacted by our pre-conceptions and expectations.
There are lots of speaker cable theories, but there exists almost no objective measurement that proves audible differences between decently designed cables....and our leader Amir has very nice things to say about Amazon basics cable.
There are a lot of measurements that prove human perceptions of hearing are impacted by our expectations and beliefs, and that the simple act of listening intensely also impacts our perceptions.
In my view that does not mean you should not enjoy your new cable. I enjoy tube amps (and tube rolling) even though I know that my tube amps are objectively not as good as solid state, and that the joy I get from them mostly comes from liking the nostalgic glow, and how they remind me of the old tube radios we listened to when I was a kid. So, I'm going to like tubes, but I am not going to spend $5000 on a tube amp.
