Op, Out of curiosity, I set up a trial of Audirvana on a Windows PC (I don’t have a MacBook M, which is the minimum requirement for macOS installation per Audirvana), and started streaming. I simply switched my Mirage USB cable from the Innuos Zen Mk3 to the PC’s USB port, so the only change in my setup was the streamer. I also made sure to match the volume for a fair comparison.
The result: the PC with Audirvana sounds significantly better than my MacBook Air running Foobar2000, as I mentioned previously. However, it still does not compare to a dedicated streamer—in this case, my Innuos Zen 3 and Rivo+—in relative terms. The dedicated streamers deliver better separation, improved spatial cues, and slightly greater clarity.
Nevertheless, in absolute terms, the PC setup sounds surprisingly good and pleasant, especially considering it is using typically noisy PC USB ports. Had I known this earlier, I probably would not have devoted as much time and money to pursuing dedicated streamers. Then there is the cost implication. To fully benefit from software features—including signal processing suites, EQ, and streaming content—you need a monthly or annual subscription, and the costs can add up over time. In contrast, a streamer is a one-time investment.
In any case, stick with what works for you as long as you are satisfied and happy with it. Thank you for bringing this up for the benefit of the group. Who says a PC or Mac can’t be a great streamer? I can even imagine one day when Audirvana is implemented directly on mobile devices with sufficient computing power—and still sounds excellent.
