I need to buy a dac to use with my active speakers.
Is it possible to use d50 as a preamp ? I will be using them with these ...https://avihifi.com/products.html#dm5
I was initially thinking of buying the d30 , as I had a passive volume control but that has just gone bust. Could you use the computers (OSX) volume control to adjust the rca ouput from the d30 to the active speakers and not use a preamp?

Within the bit-accurate playback configuration, which is recommended for an USB-DAC setup, you do not have volume control within the player ...

Not true.

Practically all players offer digital volume control which will work via ASIO/WASAPI for PCM playback. Digital volume control will of course change bits so speaking of bit-accurate playback in context of digital volume control makes absolutely no sense.

@AM88 , the answer to your question regarding software volume control with D30 is yes, you can. You can either use volume control within the player or you can use ASIO volume controls. Avoid using Windows volume control at all cost.

@Krunok Thanks I'm not so worried about "lossed bits" of music using digital volume control especially on OSX.
I was more worried about the volume function being unhighlighted and not being able to be used and just sending a full signal through the usb. That happens sometimes to some dacs I think.

As far as I know you can definitely use volume control with CoreAudio.

More info here.

Thanks for the info. I might just try the d30 rather than the d50 as the price is almost half and for me the preamp was the only thing that justified the price difference. I probably wouldn't be able to distinguish either in terms of SQ.

It(d50 or d30) could act as a volume controler but that is not the best way to playback . Digital volume control harms the dynamic range badly . The DACs are not designed to do this job .
