240 volt lines are one leg each from the two 120 volt electrical phases that enter the typical home or business.
In a town home or apartment it's possible to have only one phase available, depending on appliances and what the electrical contractor was told to do.
If your place has both phases, 240 is derived by using one each 120 volt for the hots, plus a ground. You see this configuration frequently with dryers and electric stoves with their heavy angled three pin conductor AC plugs, specifically designed so regular household plugs can't accidentally be plugged in.
If you have a three prong dryer outlet in your town home, measure with a VOM between each hot leg and ground and if you get two different readings, both very close to 120 volts, chances are you have 240 available and would only need to run from the panel to where your stereo equipment is.
At the equipment end I would use a Hubbell twist lock or go to Home Depot and get the electric dryer outlets so you don't later accidentally plug a 120 V piece of equipment into it.
All that being said, does your Linn equipment have a selector or internal jumper that allows consumer or local dealer to change between 120 and 240?
If not, returning your equipment to the factory to convert to 240 volt would (in my opinion) not be worth the hassle and expense involved.
