So what can the Sirius do? It can upsample of course, and it can change formats between PCM and DSD or vice versa. It supports up to DSD 512 and PCM sample rates up to 384kHz. It is a re-clocker, because all of its digital inputs are cached, and then re-clocked using not one but three 72fps clocks. The Sirius can also perform speaker placement compensation, and supports full parametric EQ functionality. On top of all of this, it also provides digital volume control, and while not as good as an analog volume control, in my testing I found it to be a better then using a source device (such as a streamer or a computer) to control the volume digitally.

Now some of you may wonder why you need an up-sampler. Many DACs, after all, support many different sample rates, and many argue that you cannot “create or add detail” if it is not there. We will talk about the create/add detail part a little later but let’s focus on other DACs first.
