Is 60 amp electrical service enough for high end tube system


Just purchased a new home that has a 60 amp electrical service. Do I need to upgrade to 100 or 200 amp service? How much will this upgrade cost if done by a licensed electrician. I will be running a 200 watt per channel tube amp. Any and all opinions would be greatly appreciated.
Thanks

I am sure the service is enough for the stereo, but is it enough for the stove and dryer. A lot of electric stoves have 40 - 50 amp circuits and would be a major drain on your service. A good starting point to determine if the service is up to snuff is to determine if the lights dim when turning on various electrical loads. In an old house just printing a page on my laser printer made the lights flicker. I had to get that problem fixed!
If your oven, dryer, water heater, and furnace, and range are gas, it's enough. Upgrading the main panel and lines to the power pole is not expensive, and will add value to your house. Grounded outlets are important. Two prong outlets can be grounded individually by running groung wire to a grounded water pipe.
As stated above, a 60 amp main is plenty enough for stereo but is it really adequate for the whole house? Look at your heavy loads: electric stove, dryer or water heater? Air conditioning? Large refrig. &/or freezer? Large fans or water pumps, that sort of thing. Then determine your voltage coming into the distribution panel when many (not necessarily all) of your loads are operating simultaneously. Look at this realistically, not necessarily fully loaded. Using a VOM, measure the 120V of each phase-to-neutral coming into the panel. Measure at nominal load ( just house lights etc.) compared to heavily loaded. If your lines aren't sagging too much (say 117V no load down to 115 heavy load) then the 60 amp service is adequate. Otherwise if you see a lot of voltage drop then your utility drop probably needs upgrading to 100 amp or 200
