it depends on how you are running the mono mode in the ESS, theres 3 different mono modes and you can run with 2 boards, which although larger and more expensive is somewhat neater than trying to piggyback 2 dacs to a single NTD1, which would make for a bit of a mess and longer current connections, which could easily offset any advantage.

its no different to how people are running dual mono with 2 IVY, or 2 Xxx you need to map the dac channels appropriately. so people running dual mono with any of the twisted pear stuff will not change anything when running 2 x NTD1.

i'm running 2, but for 4 channel. which is the advantage of running with 2 boards, you can run dual mono, or you can make a 2 way crossover, either digitally, or by installing active or passive analogue filters in the analogue stages
I still can't figure out how to connect two NTD1 in Dual Mono. According to BIII integration manual, in addition to IVY, it require another Sympatico to combine the two balanced output to single channel.

nah, OK maybe its not as good as I thought. the BIII FW that is, but if you have arduino, you should be able to do what i'm thinking. its possible with ackodac. you need to play with the channel mapping. dont have time for this sorry mate, this is thinking you should have done ages ago.... i'll help where I can, but you need to pick up the ball here
