The Thieaudio Hype 10 is 18Ω at 87.6 dB/mW; the Thieaudio Oracle MKII is 15Ω at 104.0 dB (no figure from the maker at all). 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 Hype 10 needs 16.4 dB more than the Oracle MKII to reach the same loudness — 17 mW against 0.40 mW.
| Specification | Hype 10 | Oracle MKII |
|---|---|---|
| Impedance | 18 Ω | 15 Ω |
| Sensitivity | 87.6 dB/mW | 104.0 dB |
| Sensitivity (voltage) | 105.0 dB/V | 122.2 dB/V |
| Power for 100 dB | 17 mW | 0.40 mW |
| Voltage for 100 dB | 0.56 V | 77 mV |
| Current for 100 dB | 31.1 mA | 5.2 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 2.25 Ω | 1.88 Ω |
| Sources that reach 100 dB out of 280 | 264 | 280 |
One caution before reading the rows. For Thieaudio Oracle MKII the maker publishes no sensitivity figure at all. The number in the table was collected when this database was first built and has never been traced to a manufacturer document, so treat every row below it as an estimate rather than a specification.
16 of the 280 sources have the power for the Oracle MKII but not for the Hype 10 — Apple USB-C dongle (US), Apple USB-C dongle (EU), JadeAudio JA11, 13 more.
3 sources are low enough in output impedance for the Hype 10 under the one-eighth rule but not for the Oracle MKII (Astell&Kern HC3, RME Fireface UFX II, RME Fireface UFX III).
2 sources stay below the audible-hiss threshold with the Hype 10 but cross it with the Oracle MKII (FiiO BTR11, Rupert Neve RNHP).
264 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.
Each model has a page of its own with the full source list, the hiss estimate and the provenance of every figure above: Thieaudio Hype 10 and Thieaudio Oracle MKII. Each figure on this page is labelled on those pages with where it came from, including the ones Thieaudio never published — what that maker publishes, counted.
