@jrareform Yes, I have tried several streamers before settling on the Rivo+, including the iFi Zen Stream (to begin with), WiiM (Pro+ and Ultra), and the Cambridge Audio MXN10. I upgraded the power supply on all of them, either with an LPS, an iFi iPower2/iPower X, or a quality power cable.
The WiiM Ultra is fine, but to my ears, the sound quality isn’t truly satisfying unless it’s paired with a DDC. The better the DDC (from PO100 Pro to Gustard U18), the better the sound quality. Nevertheless, none of these budget streamers can really compete with higher-end models such as the Rivo+, T8, Zen (Zenith) 3, or several more expensive but still affordable others.
I was very defensive previously until I tried those higher-end models — which are still considered “budget” gear by people who own truly high-end systems. I just wish I hadn’t had to spend so much time and money acquiring and testing them, only to discover that significantly better alternatives were available for just a few hundred dollars more.
