    Hi,

    I have Edifier S1000DB powered speakers. They have optical and coax inputs due the speakers including an onboard DAC. I want to connect my laptop directly to the speakers and play FLAC, MP3 etc. My laptop only has analog out (headphones), or USB ports. I want to use the speaker's DAC, so I'm trying to find a cable that will connect USB output to coax or optical input. Is there such a thing, or an adapter/digital signal passthrough of some kind? The speakers do not have USB input.

    Thanks

    You’ll need a usb to spdif converter. None of them are dirt cheap so I’d suggest one of these.

    Meridian Explorer USB DAC / Headphone Amplifier - Original Model 502552500811 | eBay

    An excellent usb dac so you could use it into the analogue input of your speakers. And it’s also a usb to optical output converter so can be used as that too.

    You’d need one of these too as the Meridian uses a mini toslink output.

    I got a Halide Bridge on eBay which does exactly this. It works really well. Allowed me to use an old laptop as a high quality audio source (basically I’d taken my last CD player to the holiday house and it was the only thing left I had with a CD drive). I picked it up for 1 Euro which I thought was a reasonable price.

    That doesn't make much sense to convert Digital to Digital, it make more sense to convert USB to Analog and go directly into the AUX port of the speaker.

    How much money are you willing to spend on this project?

    Most good USB only DACs are going to run near £100, but there are lower cost alternatives.

    This is closer to a USB to other Converter, still reasonably cheap -

    This is only a cross section of hundreds of solutions that are available.

    Also, the dac in the Meridian and it’s implemtation will be better than the one in the speakers, if they are up to showing it off.

    Thanks everyone for the suggestions and advice. I ended up going for the Topping D10 DAC $90. It has the USB compatibility I was looking for plus the ability to pass through a digital signal. Actually, it was the only reasonably priced new DAC with digital output I could find. Seems to get decent reviews.

    @dave48 I had not seen the Halide Bridge anywhere or any other cable with USB to optical conversion. That looks really interesting.
