how to run a 230 volt line from my panel??

If you are intent on doing this then get an electrician in. There could be MANY code restrictions that need to be followed.

In north american homes 230v is generally reserved for stoves and in some cases heating.

Connecting a 230v component to another of 120v may also present a problem.

Best solution - get a steup transformer - at least they are designed for the job.

Disagree about "230v reserved for stoves and heating..."
I have a 240v in my living room for the in wall air conditioner. I COULD (if I felt like it) buy a 240v power conditioner and use that 240 outlet for my stereo (the conditioner I am thinking of uses 240 but outputs 120)
So it is no big deal to install a 240v outlet in a living room. The only thing as mentioned it must have the proper duplex so it can NEVER be mistaken for a 120v outlet.

About the 240v item combined with 120v items.. A very small possibility of an issue (like damaging the 120v stuff) exists if a short developed in just the right way in the 240v item.. But if you are willing to take the risk (low) then it would be up to you.

thanks guys- Ye sthis is a separate line just for this unit- there will be nothing else plugged into it as it will be inmy stereo closet- Just want to be sure on the hook up- If I get the 20 amp breaker and wire it to a 20 amp switch- can I just use the power cord I have now and cut off the end and just get a 20amp connector and am good to go??

It's unlikely that your new unit, will have an IEC connector(inlet on chassis) that matches the one on your present power cord(http://www.internationalconfig.com/icc5.asp?productgroup=%27IEC%2060309%20%28309%29%20Wiring%20Devices%20and%20Cord%20Sets%27). If it does; you can use(NEC notwithstanding) what ever plug you choose(IF the cord is rated for 20A). Wait until you receive the component and better know what your are dealing with.

Just for perspective, every house has two separate 120 lines coming in. Combining them yields your 240. 240 appliances require two 'hot' leads, hence 240 volts.
