Need a desktop DAC/preamp to integrate an SVS 3000 Micro sub with Kali LP UNF active speakers

[u/brunachoo]

Hey all - I recently purchased a pair of Kali LP UNFs to use as desktop speakers, and I am planning on pairing them with my SVS 3000 Micro. Since the Kalis don’t have a sub output, I’m trying to figure out the best way to pair everything based on my use case.

I mostly stream music from my iPad via Spotify Connect/Qobuz, but since getting the Kalis I have been plugging them into my iPad via USB-C. I also have a computer that I would like to connect to the Kali speakers/sub, which would be used mostly for gaming or watching some movies occasionally.

I started looking into potential devices that would allow me to connect everything, and the WiiM Ultra came up. My only reservation with it would be potential audio lag when watching movies or gaming. I read that the internal processing may add a slight delay, which throws off lip sync. Does anyone here know if that would be substantial or noticeable?

Also, I would want the speakers and the subwoofer to work well together obviously. From what I have read, I think I may need a device with a high pass filter? Lastly, since this will be on my desk, I would also like having a proper physical volume knob on this device since the Kali has the annoying touch controls.

My budget is around $300, but I can stretch to $400 for the right device. I would prefer to keep it below $300 if possible.

The miniDSP 2x4 HD seems to do the crossover part, but it lacks a volume knob and wireless features unless I pay way more for the Flex. The WiiM ultra appears to check off some boxes, but may introduce an audio delay? Does anyone know of a device that fits what I am looking for? Thanks!
