You probably can't. And you, just like everyone else, have to learn to post your specs. You don't walk into a car shop and say "I want a starter engine for my car." and expect them to pop the right one up.
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. -
