It's tough to say which mod will work in which system. Also, mods seem to be system dependant, as cables are. This said, personal experience reported here is irrevalent, unless system parameters, hearing ability, and room acoustis/treatments are consistant.
I've found the modified Di/O to better my DAC costing twenty times the cost of the DAC which it replaced. Muddy bottom end? Loss in spatial info and soundstage anomolies? Not in my system.
