This product looks good from the info I have gathered so far but a few of questions if anyone can help answer.
From the site:
"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 . )
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 : ES9018 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 : 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 .
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 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 .
4, Users can setting the neutral or warmer sound for Line in with two jumpers pull / push .
5, Strong power output : 2000mW / 50 ohm (300mW class A) , 1100mW / 100 ohm (600mW class A) , 400mW / 300 ohm (Full class A)"
1) I plan to use this through USB, should I worry about the DIR module at all?
2) I like the line-in/line-out options but what is up with the OPA(opamps?) stuff? Do I need to install one of those if I want to use the compass 2's line-in?
3)Lastly, I am a little confused about the power output, I have the HE-500 atm, will it be fed the 2+ watts or the lower rated power output?
ATM, I am ready to purchase it in a default version but those questions are bugging me
