The Sivga Luan is 38Ω at 100.0 dB (no reference unit printed); the Sivga Oriole is 32Ω at 108.0 dB (no reference unit printed). This page covers what they ask of an amplifier, not how they sound.
The Luan needs 8.0 dB more than the Oriole to reach the same loudness — 1.0 mW against 0.16 mW.

One caution before reading the rows. Sivga Luan and Sivga Oriole printed a decibel figure with no reference unit, so this page reads it as per milliwatt. If it is really per volt, each of them needs far more than the table says. Why the two readings differ by so much.
Every source in the database that drives one of them drives the other. On power, the choice between these two changes nothing about what amplifier you need.
1 source is low enough in output impedance for the Luan under the one-eighth rule but not for the Oriole (Shanling H5).
3 sources stay below the audible-hiss threshold with the Luan but cross it with the Oriole (FiiO BTR11, FiiO K11 R2R, Rupert Neve RNHP).
280 of the 280 sources here reach 100 dB on both.
The Luan is more demanding than 57% of the 567 non-electrostatic models in this database; the Oriole than 23%.

| Source | Price | Headroom, Luan | Headroom, Oriole | Output impedance | Noise |
|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 14.0 dB | 22.8 dB | 0.5 Ω | 1.7 µV |
| FiiO KA11 | $29 | 22.3 dB | 31.0 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 19.2 dB | 28.0 dB | 0.6 Ω | 1.0 µV |
Of the 280 sources here, 280 reach 100 dB on both. 66 of them also publish an output impedance low enough for both under the one-eighth rule and a noise figure that stays below the audible-hiss threshold with both.
The cheapest of the 66 is the JadeAudio JA11, at $20. It leaves 14.0 dB of headroom on the Luan and 22.8 dB on the Oriole, its output impedance is 0.5 Ω against a one-eighth limit of 4.75 Ω and 4.00 Ω, and its noise figure puts the hiss floor 21 dB and 12 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
| Model | As printed | Tolerance | Standard |
|---|---|---|---|
| Luan | 20Hz - 40KHz | not printed | not printed |
| Oriole | 20Hz - 20KHz | not printed | not printed |
Sivga prints 20Hz - 40KHz for the Luan and 20Hz - 20KHz for the Oriole.
Neither range has a tolerance printed beside it, so a wider range on one sheet is not deeper bass or more treble.
Not a measurement; maker by maker.
Both have a page of their own. In full: Sivga Luan and Sivga Oriole. Each figure on this page is labelled on those pages with where it came from, including the ones Sivga never published — what that maker publishes, counted.
