If you like what you have, good. That's an excellent place to start.
Now, before you spend another dime, test every candidate IN YOUR SYSTEM and see if any of them is worth the money. That's for interconnect and speaker cable.
Then there's power. I did the following test:
1. bought a classy isolation transformer, and sited it a utility room, because they tend to growl when on duty;
2. tested three expensive power cords on a standard plug; each sounded better than the stock power cord;
3. tested same three expensive power cords on an isolated plug, and they all sounded the same as the stock power cord; and better than any from step 2.
This led me to conclude that an isolation transformer does what an expensive power cord does, except better, and for less money. And then there's the added benefit of protection of expensive equipment, which was my main consideration.
You asked what I did. That's it, and it worked for me. Tested every candidate IN MY SYSTEM. No reviewers. No know-all posters. No BS. Just experiment.
