"Look at main panel replacement if you see glass fuses."
Why? If you have a main panel with glass fuses then it's time to update the service. When I did so I opted for a large industrial panel with plenty of room for expansion.
This has made it very easy for DIY dedicated lines. I have Levinson 33's which are fairly power-happy. In total, there are 12 pair of dedicated outlets in my listening room.
Best,
Paul :-)
