Great to know, as I too have been using the Ori with iDSD, certainly drives it well but at times a bit sterile / clinical sounding, perhaps due to the Sabre DAC. A bit more warmth and mid-forward signature would be welcomed as long as it wasn't at the expense of giving up too much detail retrieval.
Also, have you tried DSD files with the S6, as native DSD decoding is a strength of the iDSD and I believe S6 does DoP. I think there is some debate as to whether DoP is equivalent sound quality to native decoding, but as they say....trust your ears and I'm glad you are enjoying this combo. I've been considering upgrading my iDSD to the Pro when released but it's likely to be $2000, and certainly S6 seems like a better value proposition...I've been wanting to try the Ori balanced and that savings could go toward a nice balanced upgrade cable for my Ori and perhaps a tube amp which the ZMF forums say synergize great with the ZMF's.
