There is a much better choice than a power conditioner but at $1k is probably more than you are ready to spend right now. And do not buy a cheap one, that will be money down the drain.
The Synergistic power cords you are looking at are the industry standards for value. I still have a Master Coupler in my system. And it is a pretty high end system. https://systems.audiogon.com/systems/8367
Since you mention depth and inner detail then keep an eye out for deals on HFT and ECT. Both are great at making speakers disappear. Check https://highend-electronics.com
If you buy a new amp or whatever you will get some improvement, yes. But frankly maybe not as much as with these. Also things like power cords, HFT, ECT, etc are more or less forever. No matter how much or what you upgrade to down the road you keep them and use them with everything. So its smart especially when on a budget to work on using things like these to maximize and get the most out of what you have before spending on something new.
