It wasn't placebo or wanting to hear differences. All cables resulted in an appreciably different sound. everything from the Curious cable to Wireworld Platinum to Ansuz Diamond $2K) to the Inakustik. in ways that made me want, or not want, to listen to the music. Changing USB cables made the DAC sound different. Still points under the Aurender made the DAC sound different. That's because I have an asynchronous-USB DAC (Hegel HD30) and use USB to connect my Aurender N100 (the only digital output that music server provides actually). However, that's not to say I dis-believe it's possible without a proven explanation. I too would love to understand the science behind the sonic impact. First with a ZENITH MK3 about a year ago. I am definitely not hallucinating, as our assigned troll makes it sound. This is change of the same magnitude of upgrading to a better DAC (I have owned over two dozen DACs over the past 15 years) Results are clear, this brings my setup to a new level. Nothing scientific, no blind tests certified by a panel, just me, with and without Phoenix USB in the path. So it’s all subjective, and I understand the skepticism.įor what’s worth: I did a few A/B tests last evening as well as today. It replaces the 5V power by one of the included Statement-level linear power supplies existing on the PhoenixUSBĪnd I already shared my own impressions of actually owning the PhoenixUSB for myself, but that’s of course one man’s data point. It regulates the 5V line from the source, helping remove some noise from the source itselfĢ. PhoenixUSB does not work at the audio level but at the USB protocol level.Īnd I am leaving out the two other aspects of the design. They are reclocking the USB commnunication between the source and the DAC. Do not confuse this with the clocking for the audio signal, they are not touching the audio signal at all. Innuos has tested on numerous DACs, some very well known in the market for its galvanic isolation, and the result is still the same - they can't really isolate the data lines so the source still matters.īasically: PhoenixUSB reclocks the USB signal with a very high-end OCXO clock, which is powered by its own power supply. This has also independent of the isolation of the DAC. What the PhoenixUSB shows is that the USB communication components themselves are affecting the performance of the DAC. What they reclock on the DAC is the audio signal that is transported via USB. I don't think people realize that the USB signal does not get reclocked by the DAC. Now that our assigned Troll for this thread deleted all his posts (good riddance IMHO), it’s probably time to repeat the most common misconception about reclocking function of PhoenixUSB:
