AC Power Question

I am repositioning my system and need to install ac outlets. I assume its a good idea to have a dedicated circuit for my system below ( stereo only). Should i have 2 dedicated circuits? 15 or 20 amps? I may also have a power conditioner in the loop as well. Thanks in advance for any thoughts and advice on do's and don'ts....
