The following is a list of digital to digital converters (and some similar components like the MScaler) that I've had in and tested.
These are listed in order of RMS jitter level upto 100khz, but I would encourage you to look at the actual spectrum of jitter too. The number alone can't provide the whole picture. The ranking order is just to provide a general picture not an absolute 'this is better' ranking.

I'll add more as I test them, but I figured this would be interesting/useful to folk looking for a DDC for their setup!

Very good and informative post. Not much DDC comparisons out there especially on measurements on jitter/noise performances. Great commendation on the time, effort, passion and share.

I have an SU-6 for sometime now as a temporary replacement for the delayed Audiobyte Hydra Hub (DDC, streamer, upsampler, format converter). Audiobyte says its shipping, don't know when it will be available locally.

What I can say about SU-6 is that its solid. Does it job well. A plus is its configurable I2S. Don't know how will the Hub will make the difference though. Since it has other functions. Will see.
