Should a high end system be flexible, or demanding?

I have left vinyl behind, but at one stage I had a turntable with three arms each with their own phono amp. I also almost always had two turntables. I was able to accommodate a wide spectrum of material.

This can be done on the digital side too. Use 2 or 3 sources, hooked to 2 or 3 DACs, hooked to 2 or 3 preamps and so forth.

Expensive, but you can have you cake and eat it too. 

An audio system that cannot play all music, all recordings superbly, is not much of a high end system. There are fundamental weaknesses, shortcomings in a system that cannot sound terrific with all genres of music and all recordings.

I had a quick peek at your system. Very impressive. It represents the opposite of my approach to audio. (Mine is strictly single driver, back loaded horn, flea powered SET etc.) Now clearly your system will do a lot of things mine won't, but I think you'd be mistaken if you think your system comes close to working as well as mine on the material mine is focused for. And by mistaken, I mean dead wrong.

Now I am not suggesting one system, or one approach, is better than another. They are simply the result of different interpretations of what good sound reproduction is supposed to be. Long story short, your system will not play all recordings superbly if by "superbly" we mean a standard accepted by every discerning audiophile. Nor will mine. However, without doubt, both our systems are high end.
