Through the balanced sockets the iBasso DX270 reaches 100 dB on 567 of the 567 models here and the Lotoo PAW 6000 on 565. Derived figures are worked out from the loads the maker did publish.

| 600 Ω | Derived | Derived |
Both makers publish a power rating. iBasso DX270 publishes at 32 Ω; Lotoo PAW 6000 at 32 Ω. The other rows are worked out from those.
The two publish at the same loads, which is the one case where the rows of this table can be read straight across.
1 headphone reaches 100 dB on the iBasso DX270 but not on the Lotoo PAW 6000 — Moondrop PARA.
565 of the 567 models here reach 100 dB on both.
Headroom is at a 100 dB SPL peak.
The widest gap on the list is the Audio-Technica ATH-R70X: iBasso DX270 has +13 dB of headroom there against +11 dB. 1 dB is about 1.4 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for iBasso DX270 because that maker publishes no output noise figure.

The Lotoo PAW 6000 costs $51 more than the iBasso DX270, and on these three axes the money buys nothing: among the 567 models here there is not one that the Lotoo PAW 6000 handles and the iBasso DX270 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper iBasso DX270 drives one model to 100 dB that the Lotoo PAW 6000 does not.
Only published figures count here; blank axes are counted separately.
