It is possible to get an 18 bit Burr Brown DAC to 95.5dB SNR, including ground isolation, output buffering, etc. Been there, done that. Never EVER want to do that again. Yes, that's 16 bits, but that was the actual spec on the device, so I don't feel too bad about that.
8x O/S (CXD-8003S), all top 4 bits individually trimmed for minimum THD. Tested at >117dB S/N and THD below 0.0015%. 1989.

And yes, they are LC-OFC potted and canned line transformers for the balanced outputs.
