Hype 10 vs Monarch MK3: which needs more amplifier?

The Thieaudio Hype 10 is 18Ω at 87.6 dB/mW; the Thieaudio Monarch MK3 is 20Ω at 99.0 dB (no reference unit printed). This page covers what they ask of an amplifier, not how they sound.

The Hype 10 needs 11.4 dB more than the Monarch MK3 to reach the same loudness — 17 mW against 1.3 mW.

One caution before reading the rows. Thieaudio Monarch MK3 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.

Where the two part company

16 of the 280 sources have the power for the Monarch MK3 but not for the Hype 10 — Apple USB-C dongle (US), Apple USB-C dongle (EU), JadeAudio JA11, 13 more.

1 source stays below the audible-hiss threshold with the Hype 10 but crosses it with the Monarch MK3 (Schiit Mjolnir 3).

264 of the 280 sources here reach 100 dB on both.

What each one needs from 80 to 105 dB

The Hype 10 is more demanding than 88% of the 567 non-electrostatic models in this database; the Monarch MK3 than 49%.

Of the 280 sources here, 264 reach 100 dB on both. 68 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 68 is the FiiO KA11, at $29. It leaves 11.3 dB of headroom on the Hype 10 and 22.5 dB on the Monarch MK3, its output impedance is 0.7 Ω against a one-eighth limit of 2.25 Ω and 2.50 Ω, and its noise figure puts the hiss floor 30 dB and 19 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
