that's too bad though that you could not get through to them. I've been reading many reviews on them and they all seem to compare it to the Total DAC at $10k more money that's a good reason to take a look and be patent. god not to free the cash up.
this line in Michael's review makes you wonder and take a closer look.
"I've spoken in the past about how the totaldac resides in the non-digital sounding arena and how not very many DACs play on that field. Two DACs that spring to mind are the dCS Rossini and the T+A DAC 8 DSD when fed nothing but DSD512 from HQPlayer. I am happy, very happy, to add the HoloAudio Spring DAC LEVEL 3 "Kitsune Tuned Edition" to this short list. "
