No matter what equipment changes you do in the future it will always be the foundation.
Here is my order of importance.
1. Dedicated circuits using 10 or 12 gauge wire (I have 3 for Digital, Analog, and subs).
2. Furutech GTX outlets. Don’t cheap out on this important part of the AC power foundation.
3. I really like the Core Tech balanced power conditioners.
4. Quality power cords. I really like the Cerious Matrix.
5. Room treatments, ASC traps, Synergistic HFT’s etc.
6. Interconnects, speaker cables. I really like the Cerious Matrix. (some may be replaced after #7 below.)
7. Then down the line investigate changing equipment.
