?: do these smsl/topping/? bluetooth amps, D12/DL200/etc, allow output to bluetooth headphones? The DL200's description says bluetooth input; so, assuming that amp has no bt output? amazon's description for this D12 is too vague; "High-end Bluetooth 5.0 chip", and the D12 manual on smsl-audio.com website has Input....USB/BT, in specifications, but no matching specification for outputs, like; Output....6.35mm/BT. why!?. why is it soo hard for manufacturers to describe what is right in front of them; if your specifications section in the manual clearly lists inputs, then why not also clearly list outputs!? Looking at a couple of bluetooth Topping amps; the product description of one says "Bluetooth Headphone amp / Bluetooth DAC", which seems to indicate bt output via "Bluetooth DAC"?..; but the other amp just talks about bluetooth w/out really explaining, anything ~ like "High-end Bluetooth 5.0 chip" for the smsl D12... how hard is it to just describe things explicitly; bt input = yes/no, bt output = yes/no!? -end rant- Thanks in advance to anyone who answers!
