"@jl35 would you consider the R-N803 and A-S801 in their “upper level”?"
The R-N803 is a network stereo receiver that I personally would not mind having with one of my secondary stereo rigs.
The A-S801 is the top model in the DAC/integrated amp line that from all I have heard and read is a very nice performing piece. Pretty hefty also at over 26 pounds.
"A-S1000,1100,2000,2100,3000" are the upper level all analog line that are built to another level and all have real wood side panels that offer a very classic look.
Look into these.
