1, The Compass 2 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 . )
DA modules : ES9018
sound characteristic is very neutral and a ton of details without
harsh, bass is speed and control .
Dual PCM5102 sound characteristic is neutral and a ton of details ,
bass is strong and rich .
DIR modules : Users
can choice the SPDIF signal feed
to either ES9018 direct and through DIR module with 3 jumpers
setting , which is simply for users choice different sound flavors .
Other DA modules must setting with DIR active model .
WM8805 sound slight warmer , support up to
192KHz .
DIR9001 sound quite neutral, support up to 96KHz .
2, The Compass 2 have Line in, users can use it as a dedicate head
amp / preamp .
3, The Compass 2 have Line out , users can use it as variable
level as DAC with preamp combo or fixed output level as dedicated
DAC .
Summarize:
Fully discrete analog stages without any OPA and couple caps in the signal channels.
( Built in DAC and head amp)
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 25000 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
