I live in a country where good home audio equipments are hard to come by. The limited options that we have here cost twice the amount you would see on amazon. The setup I have right now is Marantz CD 5004, Yamaha RX V467 receiver and mission M34 floorstanders. Now it sounds pretty great when I play stuff like Sting, but doesnt really sound right when I play stuff like Deep Purple or Sabbath. Doesnt sound as clear as they should or I think they should. I use local and pretty basic speaker wires. Will it do any good if I get monster cables? Any suggestions which wont force me to break my bank?
