One needn't be a fan or hater of J.K. Rowling to have passing familiarity with the phoenix legend.

It's the bird which rejuvenates itself by self immolation. It regularly burns to ashes only to rise again. Out with the old, in with the new.

For a reclocker with singular i/o on USB, the notion of power regeneration and/or noise-stripped signal neatly conjures up the bird myth. Innocent fans of USB audio see no call for rejuvenation. Haters will. They're aware of the 5V power line and ground which connect a computer's switch-mode power and USB network to their D/A converter. They view computer sources as barely fit for hifi purpose. They're aware also that unlike S/PDIF, USB embeds no clock signal. They could thus wonder. Why did Innuos choose to output purely on USB rather than convert to S/PDIF or I²S as most competitors do?

To learn why, Innuos would call me after receipt. They'd answer any and all questions I might have. I'd make sure—easy, that—to be full of it; questions that is.

For those who'd invoke their DAC's galvanically isolated USB transceiver to claim no possible use or need for such devices, I'll say that I haven't yet met a USB DAC which didn't benefit from an external reclocker. For those who need multiple opinions, here are two reviews from site associates John Darko and Dawid Grzyb. Many more are elsewhere. I'm quite late to this Phoenician party but not to the general game. A Soundaware D300Ref converts USB to I²S for our Denafrips Terminator in the main rig. An Audiobyte Hydra X+ converts USB to S/PDIF on my desktop to supply a COS H1 headphone DAC and pair of Fram Audio Midi 150 active speakers. I'm sold on the concept even if I'd much prefer that especially statement DACs were impervious to bolt-on mods for fewer boxes and cables. But as anyone with woofers in their speakers knows, reality barks. Occasionally it even bites.

Pragmatists brush aside 'why' and get on with reality. Give Cesar what is his was as true 2'000 years ago as it is today. Death and taxes are sure things. So is that in audio, many don't make surface sense. Most of us simply aren't engineers to get to their true bottom with real understanding. At best we repeat what we're told by people who seem to know more than we do. But about our hifi system, we're the only ones who know what it sounds like. Nobody else can predict whether this or that change will increase or diminish our enjoyment. Even if otherwise we feel rather ignorant, here we are the real experts. What else do we really need to understand? Trust your ears and settle the bill. Or not. At €2'499, today's isn't chicken but royal phoenix feed. One more review on the Phoenix then might be what you needed to confirm whether it could serve your needs?
