Lina Dac and two amp set up's?

[Ermos (Erno)]

@ARDDCS

Lina Dac XLR to “buffered” lina Amp input.

Anthony, again: UNbuffered

Buffered or unbuffered Lina AMP input

Yes, it is. Generated balanced right from the Ring DAC and run balanced all the way through to the balanced outputs, with the unbalanced being generated with separate circuitry. As Erno has linked above, the Unbuffered input is the one to use provided you are using a source device with a suitably low output impedance. This will provide higher quality than the buffered input, provided your source device can drive it properly.
