Pre amp/power amp combo allows for experimentation, and it gives a power supply to each of the pre and power. If you wanted a tubed pre and a solid state power, that would be possible. (There are some hybrid integrateds, though).
Cables also allow tweaking of the sound. So, as some see finding a cable between a pre and power as a nucance, others see it as a chance to better their system. It's all a matter of choice. As far as user interface, though, there is none better than the 383.
