PARA vs SKYLAND: which needs more amplifier?

The Moondrop PARA is 8Ω at 80.0 dB/mW; the Moondrop SKYLAND is 60Ω at 83.8 dB/mW. This page is only about what they ask of an amplifier — not how they sound, which no specification on either sheet can tell you.

The PARA needs 3.8 dB more than the SKYLAND to reach the same loudness — 100 mW against 42 mW.

Where the two part company

105 of the 280 sources have the power for the SKYLAND but not for the PARA — ddHiFi TC35Air, ddHiFi TC35AL, Fosi Audio N3, 102 more.

13 sources are low enough in output impedance for the SKYLAND under the one-eighth rule but not for the PARA (FiiO KA13, FiiO K11, Schiit Vali 2+, 10 more).

130 of the 280 sources here reach 100 dB on both. That count is about power only — the output-impedance and hiss lines above are separate questions, and a source can pass this one and fail those.

Both pages in full

Each model has a page of its own with the full source list, the hiss estimate and the provenance of every figure above: Moondrop PARA and Moondrop SKYLAND. Every figure on this page comes from what Moondrop published, or is derived from it — what that maker publishes, counted.
