Soix used a DDC with the same DAC as mine and such first hand experience makes his opinion valuable to me. However, I don’t know what streamer he was using and how much of a factor your streamer plays into what benefit you get from a DDC. Do some streamer incorporate circuitry such that the benefits of a DDC are less than with others?
I’m using an iFi Zen Stream with their iPowerX power supply — not top line stuff fer sure but reputed to punch above its weight and to compete with more expensive streamers (their customer service is basically non existent however, which really sucks). Since I’m of the opinion everything matters there may be some streamers with design features that may make a DDC less impactful — I honestly don’t know but wouldn’t surprise me — but I’d think the more important factor is the DAC and how its inputs, clock, etc. are designed. That said, the favored input on the Pegasus is i2S and I certainly concur with that, but not many streamers to date offer an i2S output so that points in the direction of using a DDC. Hope this helps.
