You seem to have all name brand components. Although I have no opinion regarding your cables, I wouldn't find fault with any component in your system. The Sony's are great speakers, and I think you can safely ignore anyone who says your system isn't good enough to hear something they hear. Sony is obviously a very big company and makes a wide range of products, from cheap and chintzy to very very good.
If sound were all that mattered, however, there wouldnt be much of an industry.
