I have a Sansui 9090 with DCM Time Windows with an istreamer hooked to my ipad and I find it sounds good. I have not regretted purchasing it in the least. I liked the isteamer so much I bought another for my office system and gave a couple out as Christmas gifts this year as well. I have three other HRT dacs including one of the first models and I think they all sound great. I have a music streamer plus in my main system that I feed 24/96 high res tracks and I personally can't tell the diference (on my speakers in my room that is) between it and some DACs costing a whole lot more.
