Lotoo PAW 6000: power output and what it will drive

The Lotoo PAW 6000 is a portable player at $1200. It delivers 300 mW into 32Ω and 32 mW into 300Ω, which ranks it 133 of 280 for raw power among the sources in this database.

Measured at 100 dB SPL it has comfortable headroom on 547 of the 567 dynamic and planar headphones catalogued here, enough but not generous on 16, only marginal on 2 and not enough power for 2. Power is published at 32Ω; the rest of the table is derived from those figures. Output impedance is not published.

The manufacturer publishes 300 mW into 32Ω. Everything else in the table above is worked out from those figures, and this table says which is which.

The balanced output is rated separately: 300 mW into 32Ω through the 4.4mm jack.

Derivation holds output voltage steady between and beyond the published loads rather than output power, because that is what an amplifier actually does. The full method is written up here.

Ordered from easiest to hardest to drive. Headroom is measured at 100 dB SPL, which is louder than almost anyone listens — a small negative number means the source still plays loud, just without reserve for peaks.

These figures come from each manufacturer's own sensitivity rating. A handful of planars — the HiFiMAN Susvara and the Abyss AB-1266 in particular — are widely reported to need far more than their published sensitivity implies, so treat a bare pass on those as optimistic rather than settled.

At 0.975 µV of output noise, here is where that noise lands in the five most revealing in-ears in the database.

This one hisses. With the most sensitive in-ears in the database its own noise lands around 21 dB SPL, which you will hear between tracks and in quiet passages.

The manufacturer does not publish an output impedance for this source. That is the one number that decides whether it leaves your headphones alone or acts as a tone control, so its absence matters more than it looks: without it, nothing here can tell you how this source will behave with a multi-driver in-ear.

If you find a measured figure you trust, the checker will work out the consequence for any headphone.

Of the 280 sources here, 10 do everything the Lotoo PAW 6000 does as a headphone output: reach 100 dB on every headphone it reaches and stay under the audible-hiss threshold wherever it does. The cheapest of them is the FiiO BTR13 at $59, against this one’s $1200 — $1141 less, and a Bluetooth receiver rather than a portable player.

The cheaper one also publishes an output impedance, which the Lotoo PAW 6000 does not — so on the paperwork it is ahead, not merely level.

This counts a headphone output and nothing else. Inputs, converters, microphone preamps, balanced outputs, the volume control, the case and the warranty are all outside it, and any of them can be the reason to buy the dearer box. What the count does say is that the three numbers a maker can be held to do not separate them.

Worked out in advance against its closest rivals: vs FiiO M17 · vs FiiO M27 · vs iBasso DX270 · vs Shanling M7 · vs Sony NW-WM1AM2. Each of those pages lists the headphones that tell the two apart.
