And I am not saying it is the "be all and end all".
But I think it meets your desire for simple, good sounding, and reasonably priced digital that will hold you over till the computer based stuff evolves, and the dust settles.
I own it and have tried to "upgrade" and replace it over the years (in the $3000-$6000 range), and have been unable to do so. All were highly regarded. Many were "flavor of the month" raves. But all left me cold and sounded analytical and "hi-fi'ish".
The tube based 'nome will give you a sound that is robust, warm, spacious and smooth. It is analogue-like and fatigue free. Great harmonics and textue. Not analytical at all. Music is rendered in an emotional way, and presented as an organic whole. Detail is suffucient, but not recommended for the listener who wants to focus on the trees rather than the forest.
I believe it is no longer current.
But that doesn't demean its performance.
Sounded great then....still sounds great now.
Good luck in your search.
