#102 Queen of Audio Ryusei: $129.00 Bloom Audio eBay
Pros: Its single dynamic driver earns a preference score of 78.8 and a smooth 1.37 dB spread in the median of 4 squig.link measurements. Bass rises about 3.3 dB above target between 60 and 200 Hz, giving rich, punchy low end and warmth that suits bassy and warm tastes. Upper mids stay on target, so vocals keep their natural tone.
Cons: Presence drops about 4.1 dB below target, softening vocal edge and snare attack. Treble is uneven, with a 6.5 dB peak near 8.4 kHz that can sharpen sibilance and a 5.5 dB dip near 11 kHz that trims air, and the low mids run 1.3 dB hot, adding some thickness.
