class=\"ez-toc-section\" id=\"Software\"><\/span>Software<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p dir=\"auto\">The firmware of the Louder Esparagus supports Spotify Connect, Apple AirPlay, and Logitech Media Server. It can receive Bluetooth audio from local devices like smartphones, and can be readily incorporated into Home Assistant for multi-room audio setups. Its open hardware and firmware allow it to run custom software or even esphome, as detailed in a previous article.<\/p>\n<p dir=\"auto\">To (re)flash the Louder Esparagus firmware, consider this user-friendly web installer: <a href=\"https:\/\/sonocotta.github.io\/esparagus-media-center\">https:\/\/sonocotta.github.io\/esparagus-media-center<\/a>.<\/p>\n<p dir=\"auto\">* Currently, there&#8217;s a minor software bug impeding effortless integration of the Louder Esparagus with Home Assistant. It&#8217;s expected to be remedied soon, but until then simply disable LED Vu in Squeezelite to bypass the issue. For more information check: <a href=\"https:\/\/github.com\/sle118\/squeezelite-esp32\/issues\/414\" target=\"_blank\" rel=\"noopener\">https:\/\/github.com\/sle118\/squeezelite-esp32\/issues\/414<\/a><\/p>\n<h2 dir=\"auto\"><span class=\"ez-toc-section\" id=\"Sound\"><\/span>Sound<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While sound quality depends largely on individual perception, and making comparisons between this $69 amp and other models in the $800+ range isn&#8217;t entirely rational, the Louder Esparagus not only delivers a powerful output but also maintains clarity. We assessed its performance using a pair of Klipsh R-50M&#8217;s and found there to be no discernible noise when the amp is at rest. We&#8217;re fairly certain the average user will find the Louder Esparagus sufficiently loud and clear to fill a living room or bedroom.<\/p>\n<h2 dir=\"auto\"><span class=\"ez-toc-section\" id=\"Multiroom_usage\"><\/span>Multiroom usage<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Tests show that the Louder Esparagus performs excellently in multiroom usage scenarios when used with Home Assistant and Music Assistant. When we attempted to sync audio between the Louder ESP32 and the Louder Esparagus, no issues arose.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Our two-week testing period has left us impressed with the Louder Esparagus. With its 25W per channel stereo output, it can vivify living rooms, bedrooms, or dormitoryspaces. Compared to the Louder ESP32 we tested earlier, this tool offers a sturdy metal casing, standard Wifi and Ethernet, and compatibility with almost any IR remote control. Retailing at just $69 and including a USB-C PD 20v\/65Watt power supply, the Louder Esparagus is a sound investment.
