1, The Compass 384 had infinite upgrade possible in future , the USB , DIR, DA, ACSS modules can exchange without solder . ( All analog signal transfer in current model for avoid the sound degrade by the modules sockets . Digital signal have the impedance match for avoid sound degrade by the modules sockets . ) USB module: USB-32 sound characteristic is very neutral and a ton of details without harsh . It can cooperation with any DA modules. Up to 32bit / 384K support. DA modules : PCM5102 sound characteristic is very neutral and a ton of details without harsh . Dual WM8741 sound characteristic is neutral but slight on the warm side and smooth . Users can setting the digital filter characteristic with two jumpers. DIR modules : WM8805 sound slight warmer , support up to 192KHz . DIR9001 sound quite neutral, support up to 96KHz . OPAs : Users can exchange the OPA chips and discrete OPA modules for Line in without solder . OPA-SUN sound dynamic ,detail and speed . OPA-EARTH sound is neutral but slight warmer . OPA-MOON sound is a bit warm and smooth . 2, The Compass 384 have Line in, users can use it as a dedicate head amp / preamp . 3, The Compass 384 have Line out , users can use it as variable level as preamp or fixed output level as dedicated DAC . Summarize: Fully discrete analog stages without any OPA and couple caps in the signal channels. Non- feedback ACSS analog output stage . Total of 6 groups dedicated power circuits are used to purify the power supply. 45W high performance transformer and more than 25,000 UF audio grade caps . High-End grade parts built in , ALPS 27 volume pot , DALE resistors, WIMA caps and Toshiba transistors , gold plate pure copper RCA sockets ect. 4 channels input : Coaxial / Optical / USB / Analog Line IN DAC / Preamp output : RCA (User can setting with either variable level as preamp or fixed output level as dedicated DAC ) Headphone output : 6.3MM SE USB Audio Class 2 High-speed Input from Windows / MAC / Linux ( We can not guarantee it can working with every Linux device ) Supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit ability . Resolutions support 16 / 24 / 32 Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz,352.8kHz and 384kHz Supports up to 24Bit/192KHz ( SPDIF input )
