Shame on you.
a forum is for questions to people like me that don’t understand.
on finance I can teach you. Audio isn’t my main knowledge.
As has been suggested before, you have read a lot of fringe audio-phoolery publication about what is “important.”
This is why Swerd, as well as myself have suggested you may be trolling.
You say you get it, then come back with another silly question. Cables, then binding posts, for example.
What we don’t know is what you have in the way of equipment and how your room is set up.
You are focusing on the absolute minutia that really does not matter.
If good Sound quality is what is important, and you are on ceramic tile floors, you should absolutely have good area rugs with pads underneath to help absorb floor bounce (reflected sound waves). You should also be looking at everything else regarding the room… exposed windows without good curtains, furniture, the “stuff of life” that will help absorb and diffract sound waves naturally.
All of that supposes you already have your Speakers positioned properly for best acoustic performance.
Cables, feet or spikes…. These are all items which can either negatively effect your goal or maybe offer as much as a .1% improvement. Sadly, they are the most expensive ways to try to “fix” something that isn’t really an issue.
Now because you asked. Spikes
couple the object on them to the floor. However, you say you have ceramic floors, which I take to mean ceramic tiling. Spikes, even with those little floor discs some spikes come with will do you no good. Your rubber feet are absolutely fine.
If…
and please read that with extra heavy emphasis!… IF you feel it necessary to spend money on perceived problems in the face of other potential problems that can matter significantly more to Sound Quality, then you can try using something like the SVS Soundpath isolation Feet or the IsoAcoustic feet.
Not because I think you need to.
But because you have thus far expressed a willingness to spend money on many things that don’t matter. …And for some, the act itself is what matters.
But again, you are focusing on the wrong things!
If you want to engage in meaningful discourse about it, we are here and many of us will offer our advice and assistance.
The first piece of that meaningful advice is to look at your room and set up and identify what actual acoustic problems might exist before you even think of spending money on silly little trinkets like after market power cables, expensive interconnects or outright phoolish speaker cables.
That’s it.
Now, one last thing, please. I already suggested you may be a troll or bot.
Prove us wrong. You’ve been asking these random questions. Many of us have offered help in he face of it all. Don’t go telling people we should be ashamed of questioning your intentions or humanity if you can’t draw a parallel between cables and binding posts and if they matter in the grand scheme of things.
That’s been answered now, several-many times.
If you want to learn something, engage with us. It’s pretty simple, really.
Cheers!
