#484 Twistura Sigma: $72.90 Amazon $72.90 eBay
Pros: Nine hobbyist measurements give this one dynamic plus one balanced armature hybrid a preference score of 70 with a smooth 2.21 dB deviation, so the midrange sounds natural. The largest peak between 1.5 and 12 kHz is only 2.1 dB, so it stays free of harsh treble spikes. At 26 ohms and 107 dB it runs easily from a phone, and it matches the rating of the NF Acous NM20, which costs more.
Cons: Treble falls about 3 dB and air about 4 dB below target, with an 8.4 dB dip near 11.9 kHz, so cymbals and spacious recordings lose sparkle. Sub-bass is about 2 dB short under 60 Hz and 3.6 dB down at 30 Hz, so the deepest rumble is restrained.
