That is one DSD-only option, although you pay more for their DSP implementation that would be left unused (and performs rather poorly). You can use it through USB and leave the network side unused as well. That is what I do with my UD-701N.
But rather better option is maybe Marantz SA-12SE which gives you SACD spinner plus USB interfaced DSD-only DAC. And performs better than the TEAC. Same story with it’s DSP features though.
Both are still more expensive and don’t perform quite as well as Holo Spring 3.
For maybe among the best DSD performance, you may want to look at T+A DAC 200. But you’ll pay some extra for secondary unused “PCM” side.
So in all cases you end up paying some extra for unused features.
Something like Holo Cyan 2 DSD could be great though. If such will ever happen.
