Can I connect 2 sources to the HDMI input in Oppo 203
I set a dual purpose system wanting good quality sound for music and adequate sound for surround sound. I have an OPPO with the front left and right analog outputs ran to a parasound a23 then to a Martin Logan vantage electrostats. The other channels are just powered by 2 monoprice amps one for rear left and right, the second bridged to a Martin Logan motion 8i center. I just bought a bluesound vault 2 and due to my lack of knowledge and forsight I realized I don't have an input got it. Vault 2 has both digital and analog outs. Can I add it some how. Don't know if OPPOs dac is better or vaults 2s so don't even know if I should digital in to OPPO or analog in to parasound. Or maybe there's no way without adding a preamp. I'm talking over my own head at this point.
