The Thieaudio Hype 2 is 16Ω at 104.0 dB (no figure from the maker at all); the Thieaudio Origin is 9Ω at 102.0 dB (no reference unit printed). This page covers what they ask of an amplifier, not how they sound.
The Origin needs 2.0 dB more than the Hype 2 to reach the same loudness — 0.63 mW against 0.40 mW.

One caution before reading the rows. Thieaudio Origin printed a decibel figure with no reference unit, so this page reads it as per milliwatt. If it is really per volt, that model needs far more than the table says. Why the two readings differ by so much. For Thieaudio Hype 2 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.
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.
11 sources are low enough in output impedance for the Hype 2 under the one-eighth rule but not for the Origin (FiiO KA13, FiiO K11, Schiit Vali 2+, 8 more).
280 of the 280 sources here reach 100 dB on both.
The Hype 2 is more demanding than 26% of the 567 non-electrostatic models in this database; the Origin than 24%.

|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 15.8 dB | 11.3 dB | 0.5 Ω | 1.7 µV |
| FiiO KA11 | $29 | 27.9 dB | 23.4 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 24.8 dB | 20.3 dB | 0.6 Ω | 1.0 µV |
Of the 280 sources here, 280 reach 100 dB on both. 60 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 60 is the JadeAudio JA11, at $20. It leaves 15.8 dB of headroom on the Hype 2 and 11.3 dB on the Origin, its output impedance is 0.5 Ω against a one-eighth limit of 2.00 Ω and 1.12 Ω, and its noise figure puts the hiss floor 13 dB and 13 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
Both have a page of their own. In full: Thieaudio Hype 2 and Thieaudio Origin. 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.
