Found this:

could this be of some use?
I'm thinking of 8 balanced innputs (from adat) via maybe some ON/OFF switches to some kind of arrangement of these.

240 Euro per balanced channel ?

I once saw an active solution based on a chip named PGA-2311 (there may be newer versions) in Elector April 2004 in the 10 Euro range per channel
specs are 120 dB dynamic, 0.0004 % THD+N

cheers, Tom

I could not find any prices, but now i understad it's far out
