My point was that the DAC+subwoofer out should exist given that SMSL and others make DAC/AMPs that include subwoofer outs and that cost less than $200. Examples include SMSL's SA300 for $140 and A300 for $200. Would either of these units test well? They're cramming a lot in for <$200, including DAC, AMP, SW splitting, bluetooth, etc, etc. Also, I would agree that they may not be managing the relative delays between the ampliflied channels and the SW out, but that would be known from testing. But to be realistic here, we are seeing all sorts of technologies at ever cheaper prices so there's no reason to say "that's not possible" because minidsp is doing that and more for $500, and SMSL is doing it for <$200 at an unknown quality. All I'm asking SMSL to do is change their product configuration slightly, or for someone to explain in technical terms why the chipset cannot be configured in this way. I really don't think it's a big ask and well within the permutations of the purpose of this forum. I just hope someone from SMSL or Topping is reading these threads.
