The thing about hifi that I find intriguing is that the better the sound your system produces, the more. you will want to listen to it and I think most people would accept that.
So a key question in hifi is "Why do I prefer 1 system's sound to another system's sound",
The answer lies in the fact that sound waves and your brain are actually the system and your kit is not the final arbiter. One of the most important concepts in hifi (at least in the area of high end hifi) is synergy, which is largely the difference in sound quality between systems.
Sorry for the quasi-philosophy but you will recognise this theme in my posts and it is my guide through the complexities of the hobby.

If you walked into my house now it would be a step back in time for you :-)
I will give details of my kit a little later if the thread lasts
