Hello, I currenty have a Sony SRT-DG820 receiver and a SS-FCR6000 speaker setup: SS-FCR6000 : Speakers : Hi-Fi Component : Sony Asia Pacific As input I have Sony Music Unlimited(.flac quality?...) & BD movies. I always thought that the sound was mediocre(at best). Is there a way to improve this setup: - replace the cables from the A/V to the speakers (the people who seam to know what they are talking about say that the cables provided with the speakers are Bad) - add a subwoofer? - any other option? I am interested in sound quality at low / medium volume, I don't need loud / more power. Thank you for your time.
