#72 ThieAudio Monarch Discontinued eBay
Newer model: the ThieAudio Monarch MKIV, ranked lower, rated 4.4/5, released Jul 2025. See every ThieAudio Monarch generation.
Pros: Measured response gives it an excellent Harman preference score of 81 with a 1.59 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. It uses 1 x 10mm dynamic + 6 x balanced armature + 2 x electrostatic with an easy 26 ohm load.
Cons: Discontinued, so it is mainly found used. A 4.5 dB peak near 7.9 kHz can make cymbals and sibilance sound sharp.
