Can I rewire an audio amplifier with a round pin plug to fit sockets in living room made for lamps?

Basically I just bought a home theatre system but our living room has 2 round pin 5amp plugs that are locaed where I would like the amp and rear speakers. Can I wire a round pin 5 amp plug onto the amp and use the round pin sockets? Or does an adapter exist that I could use? (UK)
