buy the Bose Wave system (35k) if there is a problem of space,it just a single piece, is really small but has pretty good sound.otherwise,here is a suggested combination:
Marantz CD5001 CD player(15k)
Wharfdale Diamond 9.0 speakers(8k)
Yamaha AX-396 amplifier(16k)
spend the rest 1k on good cables.
also,this is only a suggested combo,so go to some AV shop and ask them to suggest some combo.try and listen to the combo before u buy it.
