Since you are considering Nagra, have you looked up Wattson Audio (owned by CH Precision). Their Emerson Analog and Digital Bridge is very similar to Nagra without the proprietary N-Link. If you have a DAC that can accept N-Link then Nagra Streamer makes more sense.
I am very likely purchasing Emerson Analog in next week or so. At $1750, it appears to be a heck of a bargain.
