Sonore Streamers

[Confused]

I have an Aurender N100H. I like the analog side. When I heard Leonard Cohen's voice, it seems Leonard is in my living room. In counterpart, I like also Air 3. More air between musicians, better soundstage but lack midrange and bass of my Aurender. So, the question: Does the Micro rendu is the best of both worlds? At the same time, I can't imagine a 700$ kit can beat a streamer of 3500$. Am I right? In search of a better sound

I think it is impossible to answer the best of both worlds question without trying one yourself, with your ears and system.  As for the price difference to the Aurender, it's not a like for like comparison.  The microRendu is a renderer only, you need to add some sort of computer, file storage, power supply.  The Aurender has all you need in one box.  Plus the Aurender is a very nice looking box, frankly, the microRendu isn't!  Taking everything into account, spec a microRendu up to Aurender levels, and there is not much difference in cost.
