On power, yes — all of them. Every one of the 34 desktop DAC/amps in this database reaches 100 dB SPL on the Shure SE215, which needs 0.20 mW at its 17Ω.
Power is one of three questions and the one that goes wrong least often. The other two — whether the source’s output impedance leaves the frequency response alone, and whether you will hear its noise floor — are answered further down, separately, because a source can pass one and fail another.
The cheapest one that does reach it is the Aiyima A2 Pro at $75, which delivers 80 mW into 17Ω — 26 dB of headroom over the 0.20 mW this headphone needs for 100 dB SPL.
100 dB SPL is a peak level, not a listening level. If you listen at 85 dB the same headphone needs 0.01 mW, which is 15 dB less, and the answer above changes for most of the category. The model page has the full ladder.
Under the one-eighth rule the Shure SE215 wants a source below 2.12Ω. Of the 19 desktop DAC/amps here that publish an output impedance, 17 are under it and 2 are not.
The furthest over is the Matrix mini-i Pro 4 at 11Ω, which is 5× the ceiling. Above that threshold the source stops being a volume control and starts being part of the frequency response. The simulator shows what that looks like.
The other 15 publish nothing at all on this, so they are not on either side of that count. This site leaves them blank rather than assuming a figure.
Hiss depends on the source’s own noise floor and on how sensitive the headphone is. At 107.0 dB/mW and 17Ω, the Shure SE215 turns one microvolt of source noise into about 5 dB SPL — and the threshold where that stops being noticeable in a quiet room is around 20 dB SPL.
Of the 10 desktop DAC/amps here that publish a noise figure, 8 stay below that threshold with this headphone and 2 cross it.
The worst of them is the FiiO K11 R2R, whose published 7.2 µV works out to 22 dB SPL of hiss in these. The hiss calculator takes your own figures.
The remaining 24 publish no noise figure, so they cannot be placed on either side.

Sorted by how many of the three questions the source answers well, then by price. A blank in a column is a blank in the manufacturer’s own documentation, not a zero.
