Previous Thread: https://www.head-fi.org/f/threads/best-smartphone-for-audiophile.662095/ Please help rectify my Table if spec is wrong. Any recommendation is welcomed. =============================================================================== Google Doc for Smartphone Table https://docs.google.com/spreadsheets/d/1nhMd7oKzwauEanwUndqU5orN8T18JCm3VllomhTWqsc/edit?usp=sharing =============================================================================== Note: "Recommended" is based on my preference only. - From 2013-2015, I use UE900 as reference. - 2016-2017 I use 1964 U12 + Brimar Cable as reference. - 2018 onward, I use Fitear 335DWSR + custom cable (VK) Always take this list with a grain of salt. Remember, you have no need to believe my opinion will be same as yours. You always have your own preference and ears to believe in yourself. Note2: Price Range is just approximate number and might vary in different countries. For some devices, it is based on second hand price because I can't find the whole new one ever. Inconvenient Truth The best way to enjoy real and pure music is from Stock music player because it is the only way that software engineer can bypass android’s 48kHz sampling rate limitation and let you enjoy native sampling rate when 44.1KHz is using 22MHz clock and 48kHz or 96kHz are using 24MHz clock with no sampling rate converter. So it is the true sound that company proudly gives to you. Good News: Neutron is supporting bit-perfect playback for most Hi-Res android device. For those who own ESS, AKM chip based smartphone and love Neutron music player's simple UI with great Network Playing Functionality. Please try setting in Audio Hardware Setting in the app by following http://neutronmp.com/forum_nmp/viewtopic.php?f=3&t=4014 It is working really well with my vivo xplay6.
