@cat_doorman I think you are on the right track with power. In my experience cables and power conditioners will provide you with that last 5-10% and help bring it all together. Cables are like tires, they link the performance together. You want to have your engine and suspension tuned before buying performance tires. If things are out of alignment tires good tires are a waste of money- although you might feel a difference.
You have a very high efficiency speaker. That gives you a lot of flexibility with low powered amplifiers. There is plenty of light reading out there on what amps pair well with them- that's where I'd start. That will likely lead you to examine your source. That might lead you to examine your power, etc.
You will find out soon enough if you enjoy cycling through gear, buying, selling, trying different sounds, etc.- that's a real part of the hobby for some audiophiles. If your fortunate, your partner will be accepting of your relatively benign hobby. If you start looking for enjoyment in the Fedex delivery more than your family, you need to re-examine your situation and what's really "missing".
