The combination of great sound and great value proved very successful.\u003c\/p\u003e\n\u003cp\u003eAfter 3 years Allo felt the need to upgrade the Boss. The only questions was, how could they make the Boss2 sound \u003cem\u003eeven better\u003c\/em\u003e?\u003c\/p\u003e\n\u003cp\u003eFor sound quality, they decided to use the new Cirrus Logic DAC CS43198 as a master (another first from the Allo team). Unlike the PCM5122, it has excellent THD (-120 vs – 83). Unlike Ess, the sound is “darker” (not bright, low out of band noise).\u003c\/p\u003e\n\u003cp\u003eAllo are using over 30 LDOs (as usual), two super caps and countless filters. They also upgraded the power input filtering with common mode chokes.\u003c\/p\u003e\n\u003cp\u003eThe Boss2 Player \u003cstrong\u003eincludes a Raspberry Pi 4 4GB\u003c\/strong\u003e board and an aluminium case, along with an OLED screen and IR remote (no PSU included). Whilst specialist low-noise power supplies are the ideal power source, standard USB-C power supplies are perfectly compatible (may degrade the THD by 1-2db).\u003c\/p\u003e\n\u003cp\u003eThe Boss2 Player is a meaningful upgrade over the original Boss in terms of sound quality (measurements, THD \/ Jtest) and value.\u003c\/p\u003e\n\u003cp\u003eIn terms of WiFi performance of the case, in Allo's tests, the Boss2 Player plays reliably at around 5m or less from the router. Using WiFi dongles will increase the range substantially.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes \u003cstrong\u003eRaspberry Pi 4 4GB board\u003c\/strong\u003e pre-installed\u003c\/li\u003e\n\u003cli\u003eIncludes Aluminium case with OLED display\u003c\/li\u003e\n\u003cli\u003eRemote control included\u003c\/li\u003e\n\u003cli\u003eDAC CS43198 (192 kHz\/32bit )\u003c\/li\u003e\n\u003cli\u003eDAC output is selectable (1.7Vrms or 2Vrms) .\u003c\/li\u003e\n\u003cli\u003eSampling Frequency 44.1 kHz to 192 kHz range.\u003c\/li\u003e\n\u003cli\u003eDual Ultra-low Phase noise NDK SDA oscillators are used for master\u003c\/li\u003e\n\u003cli\u003eClock generation.(MCLK)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBoss2 Player, includes:\n\u003cul\u003e\n\u003cli\u003eRaspberry Pi 4 \u003cstrong\u003e4GB\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAluminium case with OLED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eRemote (batteries not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePower supply and SD card not included\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUser Manual including setup and software configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e*As of 15\/07\/2021 this kit has upgraded from a 2GB Raspberry Pi to a 4GB board, with an increase of price to reflect the higher model.
