Any audiophile use computer (MacBook) as your audio streaming source?

Can you post the link for the PC? I have a fanless PC for my office work, but it only has RJ45.

Supermicro is the first brand that came up. There may be less expensive options out there.

The need for a DDC is very system-dependent. Making blanket statements (like some folks) about its necessity often overlooks the specific characteristics of one’s setup. If a system already has a clean digital source, like the iFi Zen Stream, which excels in minimizing jitter and electrical noise (see below) as compared to the state-of-the-art DDC like Singxer SU-6 and Holo Red, adding a DDC could indeed be redundant or overkill.

In such cases, the additional conversion step could introduce unnecessary complexity or even compromise sound quality due to the increased signal path. As with any audio component, the key is knowing your system's strengths and weaknesses before deciding whether to introduce something like a DDC.

@lanx0003  Well, I use a Denafrips Iris Fed from my iFi Zen Stream (with iPowerX power supply) and the improvement is significant.  I bought the Iris used so I could just re-sell it if I didn’t notice a difference, but it’s not going anywhere.  So much for measurements being the end all be all.  And BTW, an SU6 or Holo Red is far from SOTA as DDCs go.
