Meze POET: how much amplifier do you need?

The Meze POET is 55Ω with a sensitivity of 101.0 dB/mW, which is 113.6 dB/V. To reach 100 dB SPL — genuinely loud, louder than most people listen — it needs 0.79 mW, or 0.21 V across the drivers.

That puts it in the easy category. A phone, a laptop headphone jack or the cheapest USB dongle will drive it to painful levels. Of the 280 sources in the database, 280 have comfortable headroom. The cheapest portable source that does the job is the Apple USB-C dongle (US) at $9.

Sensitivity here is in dB per milliwatt. Manufacturers often quote dB per volt instead and leave the unit off, which is the single most common reason online calculators give answers that are 10–15 dB wrong. The converter explains the difference.

Meze publishes this directly as 101 dB SPL/mW (at 1 kHz), per milliwatt, so nothing was converted.

The maker adds a power recommendation of its own: Meze publishes no power handling and no recommended amplifier power for the POET; the only level-related figures are "Maximum SPL: >130 dB" and "Total Harmonic Distortion (THD): <0.05%" (no SPL or drive level is attached to the THD condition).

Most people listen between 75 and 85 dB. The 100 dB row is the one worth planning around: it gives you headroom for dynamic peaks without designing your system for a volume that would damage your hearing in under fifteen minutes. The safe listening calculator puts numbers on that.

Every source in the database, judged at 100 dB SPL into 55Ω. “Headroom” is how much power is left over above what the headphone needs — 10 dB means ten times the required power, which is what you want for dynamic peaks.

Hiss. At 113.6 dB/V these are sensitive enough to reveal a source's own noise floor. The noisiest source in the database, the Schiit Vali 2+, would put its hiss at roughly 22 dB SPL in these headphones — clearly audible in quiet passages. The hiss calculator lets you check your own amplifier's noise figure.

Output impedance. At 55Ω these want a source output impedance below 6.88Ω to satisfy the one-eighth rule. 34 of the 280 sources here miss it, the worst being the Bottlehead Crack (OTL kit) at 120.0Ω. Above that threshold the source starts shaping the frequency response. Check yours here.
