I am just a couple of weeks into this new project. I recently decided to break away from the out of the box Bose system I've had for years and build a nice component system that will give me clean, crisp, quality sound. I tend to go overboard when taking on new projects so I'd like some guidance on this journey to hopefully save time and money. I purchased a Pioneer VSX-822 receiver to handle all of the HDMI sources. My main audio source is a Mac mini (mid 2010). I have a Vizio 3D bluray player and the display is a 6000 series LED Samsung TV. My speakers are B&W CM1's. I mainly listen to blues, jazz, trance techno and occasionally Hip Hop. There is also the movie aspect like to keep. My friends tell me I need better speaker cable, a power conditioner, a 2channel amp and a sub. What do I really need. What I have sounds really good but I know I can take it to another level. Any advice would be appreciated.
