Jh20s,
The tube change can be dramatic. As can the upgrade in power cord. Most used cords can be bought and sold for the same price if you decide it's not what you want. From my experience, I never heard the capability of the Jolida until I put a very good PC on it. In my case, when I went to a Wolff Carbon PC, I could not go back to the Signal. Just my experience.
Best of luck,
Howard
