meynaf: Although I've owned quite a few CBM monitors over the years, I haven't tested them all, nor do I need to. They all have shitty little speakers which have poor bass and treble reproduction.
Nothing sounds "crap" on a good hi-fi system. I find it strange that you seem to believe playing music on a better quality system can make it sound worse. That's simply not the case.
hansel75: Yes, the setup does sound good (not as good as indigolemon's though!) I've actually been considering swapping the Yamaha receiver with a NAD (or similar) stereo hi-fi amp as I do not have a surround sound setup in this room.
I've had the neighbours across the road complain about the sub vibrating their house too much. That's one complaint I was quite proud to receive
