What is the best system one can make under $5000


Hi,
I am new to speakers in general and have a couple of decent headphones. What is the best system one can hope to create with a budget of $5000. It is ok to include second-hand components as well. It should allow a turntable and at least one optical input and headphone output.

The listening area is 13ft X 20ft.

Thanks in advance for your advice.

You really need to let us know what aspects of sound reproduction are most important to you so you get recommendations more relevant to your specific preferences.
@soix, I am looking for a relatively fast speaker and will not be playing the loudspeakers necessarily loud. As for reproduction, I would like a system without much coloration. 

As for tube vs solid state, I would like to lean towards a system with least maintainance.

It seems like exaggeration is the primary tool of a lot of would-be audiophile critics.
