Simaudio also has the 791 Pre/DAC/Streamer which is $16k vs $25k for the 891 so that might be another avenue to explore (I don't know what the differences are). I suspect that mating either of these with your 861 would produce detail in abundance and you would have a great two box solution. A nice side benefit is that the Sim integrates easily with TV with HMDI ARC.
