1- I get a humming\/buzz from the modi 3, This happens on 3 different systems. The only way not to get the hum\/buzz is by using a passive pre and not going past 1\/4 volume or less, anything past that and the hum\/buzz is back. This happens even if nothing is plugged into the modi ( except rca's) Tried 4 different sets of rca's, still happens, nothing but rca's hooked up.\n\n2- The modi3 is only supposed to be capable of 24 bit 192000 hz. Yet my computer is telling me it (modi 3 ) is capable of 32 bit 192000 hz. Does this seem strange to you ? My computer has correctly identified all other dac's . Compared it to two kids dac's, Topping D30 and a SMSL Sanskrit, it identified them to their exact specs. Plus on the Halo P5 it identifies it's dac's specs correctly.
