I use this for 16 input channels of my heavy modded Ghost 32 Classic for final analogue drums mix. In this scenario, the sterile D/A is a must, especially for already well mixed ITB drums. Before I was not a fan of RME and Ferrofish soind/conversion, but with the time I understood why clean/sterile conversion is also a must - just being used in the later stages of the Productions (mixing or pre/mastering). I would definetely buy another Pulse/Ferrofish converter. Also, the difference between 20 and 24dBu isn't really a difference..(or even 18 vs 24, in or out), especially when hybrid mixing includes several parallel sum busses and/or several and different analogue circles.
