You are both correct.
Streamers are nothing but computers, and often not very good ones (think Raspberry Pi 4 or 5) unless you’re in the mood for something like a $31,000 Taiko Extreme which, besides being an exquisite piece of kit, packs serious computing horsepower.
To @soix ’s point, quality power supplies, galvanic isolation, clocks, etc. do make a difference, and they should all be part of any serious audio PC build. The aforementioned Lucas Audio does just that for you, but by the time you’re done with him you’ll have spent near-Taiko money. You can also build it yourself; if so, expect to spend in the neighborhood of $4-5k on quality components.
But those of you who once used a mac mini or some such in your digital chain and then come here to denigrate PC network streamers on the basis of your one (admittedly dismal) experience, it’s like saying you drove a Nissan Leaf back in 2010 and it sucked, therefore all electric cars suck. Teslas don’t suck, neither do Lucids, and a $50 Raspberry Pi build will better a mac in terms of sound quality.
So I think it's time to give PC streamers their due. Done properly, they will rival the SQ of anything Aurender or Innuos make, plus they will give you unmatched software flexibility, upgradeability, and power.
