So, I have a Matrix M-Stage Amp + DAC stack (so, the DAC is the standalone, not the cheap one that comes with the USB version of the M-Stage amp), with a pair of Sennheiser HD-650's.
I also have a really cheap pair of powered computer speakers by Altec Lansing. Is there any way I can use both the Sennheiser HD-650 and the cheap speakers running out of the computer and through the M-Stage stack?
I had assumed I could just use the preamp outputs on the M-Stage amp, to drive the computer speakers... thinking they are the same as the line-out. But now I'm thinking I have the wrong idea about what the preamp is, considering I just connected them right now, and no sound is coming out.
There is only one output for the DAC, which would be used for the amplifier, so it seems there are no options of running the speaker out of the DAC as well.
I do have onboard audio with my motherboard, so would I have to do a song and dance with the onboard audio and the M-Stage DAC to get both headphones and speakers running?
I could connect the M-Stage DAC with the onboard audio through optical for the headphones, and run the speakers from the onboard audio. I am hesitant to do that, however, because I've read the quality of optical outs vary from source to source, and given that my source is onboard audio, I'm assuming the optical output quality won't be very good.
Or is it possible to use onboard audio, and have the M-Stage DAC installed through the USB connection at the same time? Or would there be driver conflicts?
Or are there any other options of running the speakers out through the M-Stage stack, and not having to deal with the onboard audio at all?
