i have a pair of yamaha HS50M monitor speakers and a HS10M Sub which I hope to use as a 2.1 system in my new living room. Has been wondering how to implement it as the speakers only have XLR and Quarter-Inch inputs. Was considering getting an amp and output audio thru RCA or Heaphones out so I can control the volume with multiple RCA inputs(Blu-ray, Set-top box, Game console, etc...) going in the amp. Any suggestions? If not I'll place them in my work room and get a set of HTS for my living room.... But the sound from these speakers are really great.
