On power, yes — all of them. Every one of the 69 desktop amplifiers in this database reaches 100 dB SPL on the Audeze LCD-5, which needs 10 mW at its 14Ω.
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 JDS Labs Atom+ (2nd gen) at $99, which delivers 438 mW into 14Ω — 16 dB of headroom over the 10 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 0.32 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 Audeze LCD-5 wants a source below 1.75Ω. Of the 49 desktop amplifiers here that publish an output impedance, 44 are under it and 5 are not.
The furthest over is the Bottlehead Crack (OTL kit) at 120Ω, which is 69× 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 20 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 90.0 dB/mW and 14Ω, the Audeze LCD-5 turns one microvolt of source noise into about -11 dB SPL — and the threshold where that stops being noticeable in a quiet room is around 20 dB SPL.
Of the 21 desktop amplifiers here that publish a noise figure, 21 stay below that threshold with this headphone and 0 cross it.
The remaining 48 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.
