This time last year that was my predicted path. In my case the streamer failed on my 505 putting me off the notion of putting everything in one box So plans to spend over three grand on the natural upgrade to the 505 evaporated. So now I am using a Holo Audio Spring 3 with the optional pre-amp stage. No reliance on firmware updates, discrete components for the most part so fixable in the majority of cases. That will be accompanied (after a snap decision taken last weekend) by the Holo Audio RED streamer/DDC. Holo Audio electronics with Raspberry Pi CM4 processing allowing a huge choice of streaming options ranging from the very simple Ropieee for Roon which I use, to LMS to MoOde and a plethora of other options. If It works on a Raspberry Pi, it works here. I just have to wait 4-6 weeks for delivery!😉A TEAC ud701N arrived in Jan, replacing a NT 505, as the final piece in the puzzle.
