I'm looking to spend under $500 for some studio reference monitors (powered) and need it shipped to Santiago, Chile. As a classical musician I prefer studio reference monitors to get the pure quality of music. I had some M Audio AV40 speakers for years in USA which were nice considering the price I paid for them. I'm looking to step up my game a bit. I'm using some really crappy speakers now with such a heavy low end I really can't stand it. Are the Yamaha HS50M or HS80M a good choice?
