I'm actually considering these two dacs as well. Though my top two in consideration are the Totaldac D1 Dual and the Rockna Wavedream Balanced.
For me, the Rockna is number one on my list, as it is a true balanced dac and my system is all balanced. However, the TotalDac is beloved and reports make it sound wodnerful. I know someone who has a Formula, bit not the xHD. It sounds wonderful in his system, but I've not gotten to hear it in mine.
