A manufacturer produces at a price point. This means that compromises are made in terms of materials, parts, labor and the law of dimishing return to meet a price target. That's when customization comes in. High-end audio and video fidelity are really all about fine-tuning products and the assembly of parts to attain optimal results. In these days of mass production and packaged goods, we overlook this simple economic truth. Thus the end-user need to upgrade to meet personal aspirations to change, enhance and heighten overall performance.
