I wonder how 2xOPA 627 (with adapter) will sound? Heard it HiQ stuff, but price is also hi.
Measured today my front channel DC voltage (caps shorted and ad8620 as opamp) and it showed 180mV. Kind of high or what? Of cource amplifier should have cap against DC of its own and it wont damage headphones but it's kind of hi anyway and caps should be unshorted?
