The imersiv D-1 should never be used with a preamp since you lose resolution. It sounds terrific direct to amp. I always used to say that my setups sounded better with DAC to my Benchmark HPA4 or LA4 preamp and then to amp. The imersiv D-1 was the first DAC that broke that rule for me and I sold the HPA4. The first time in over a decade where I do not have a HPA4 or LA4 preamp.
The Meitner MA3i is the second DAC that I have heard that sounds terrific straight to DAC.
I am also starting to open up to take a slight hit in streaming performance to use Ethernet and forgo the better fibre streamer. I did ROON Grouped streams and was able to easily hear the difference between Ethernet and fibre on the MA3i. The difference was small and if I go with Ethernet, I eliminate a bunch of gear.
