Letters to the editor: 3 ways to juice your Chromecast Audio

  • In response to a recent post on SoundCloud and the Chromecast Audio, David D. writes an email that (for once) doesn’t try to extract more information from yours truly but provides some intel of its own:

    “Subject: How to kick the Chromecast Audio puck up a notch or two for peanuts.

    First. Open Google Home. In settings, enable full dynamic range* [see footnote 1 – Ed] for the Chromecast Audio. Free.

    Second. Purchase a UGreen Micro USB to RJ45 Ethernet Adapter with attached USB Power Supply Cable, which is specifically designed for the Chromecast Audio at a cost of about $17 USD from

    The micro USB power port on the Chromecast Audio also has live digital audio contacts that Google does not advertise or promote. With the UGreen ethernet adapter, you can input both power and audio [data] simultaneously thru the micro USB port. You now have a wired and powered network endpoint/renderer instead of a lo-fi wifi device.

    Third. Purchase an iFi Audio 5v audiophile wall wart power supply for $49 USD and connect it to the power leg of the UGreen ethernet adapter and plug it into a handy electrical outlet.

    The SQ of your Chromecast Audio will now be noticeably improved.

    Total cost (including the Chromecast Audio): about $101 USD. Try it; you will be glad you did.”

    More emails like this, please.

    Footnote #1: From Google’s support pages: “When Chromecast Audio is connected through an optical interface (see here for compatible cables), it will always use Full Dynamic Range. Setting Full Dynamic Range to OFF won’t have an effect as it will remain ON.”
