DACs that upsample to DSD internally?


Hello Everyone,

I'm wondering if we can form a list of DACs that are capable of upsampling PCM to DSD internally? I realize there are various software programs that could do this on the fly from your PC. But for the truly computer illiterate among us (like me) who find learning to use such programs incredibly frustrating, it would be great to know which DACs can to this. I only know of the Directstream. Thanks to all!

Maybe I used the wrong term. Maybe it should have been oversampled or resampled. At any rate, I have over 1,000 CDs ripped to wav files and have used more than one NOS DAC. I found a lack of detail in them. I would like to listen to them in DSD format as many many people say it sounds wonderful. 
Format conversion is probably the most accurate terminology.  I'm not sure that converting to DSD will give you more detail.  If anything my Esoteric when used in that manner sounds smooth, actually very smooth.

How did you come to the conclusion that your DAC was the cause of the lack of detail?
