Its about the filters you need before the converter. at 44.1kHz they need to be extremely steep, and create ripple. Though I guess 96 kHz is usually good enough, I can hear a difference to 192 kHz as well. The result is much cleaner and more transparent. If you down sample afterwards, you don't loose as much, as it is possible to build ideal filters in the digital domain. But I don't know of any device which would do that directly... High end fundamentalists would rather buy four times the processing power and keep everything at 192 kHz... The price, size and weight of the R-44 is aimed at that market...
