Both are portable players, $1149 against $1200. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
The iBasso DX270 reaches 100 dB on 566 of the 567 models here, the Lotoo PAW 6000 on 565.
| Specification | iBasso DX270 | Lotoo PAW 6000 |

A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
| Load | iBasso DX270 | Lotoo PAW 6000 |
|---|---|---|
| 32 Ω | Published | Published |
| 150 Ω | Derived | Derived |
| 300 Ω | Derived | Derived |
| 600 Ω | Derived | Derived |
Both makers publish a power rating, which is less common than the table above makes it look: of the 280 sources here, 209 publish a figure at at least one load and only 2 publish one at all four. iBasso DX270 publishes at 32 Ω; Lotoo PAW 6000 at 32 Ω. Every other row is worked out from those — between two published loads, or beyond them holding voltage constant, which understates rather than flatters.
The two publish at the same loads, which is the one case where the rows of this table can be read straight across.
What each of these labels means, and why a derived figure is still worth printing, is set out in how this data was built.
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. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
The counts above say how many models the two treat differently. This says by how much. The same 8 headphones appear on every page of this kind, ordered from the easiest to drive to the hardest, so a row can be read across pages as well as across columns. 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. That is a gap in the specification, not a quiet amplifier, and it is left blank here rather than filled with a plausible number.
| Headphone | Impedance | Needs | iBasso DX270 headroom | Lotoo PAW 6000 headroom | iBasso DX270 hiss | Lotoo PAW 6000 hiss |
|---|---|---|---|---|---|---|
| Shure SE846 | 9 Ω | 0.04 mW | +35 dB | +33 dB | not published | 14 dB |
| Campfire Audio Andromeda 2020 | 9 Ω | 4.0 mW | +15 dB | +13 dB | not published | -6 dB |
| Audeze LCD-2 Classic | 70 Ω | 0.79 mW | +24 dB | +22 dB | not published | -8 dB |
| Beyerdynamic DT 1990 Pro (250Ω) | 250 Ω | 0.63 mW | +19 dB | +18 dB | not published | -12 dB |
| HiFiMAN HE400se | 25 Ω | 7.9 mW | +16 dB | +15 dB | not published | -13 dB |
| Audio-Technica ATH-R70X | 470 Ω | 1.6 mW | +13 dB | +11 dB | not published | -19 dB |
| Sennheiser HD 600 | 300 Ω | 6.6 mW | +8 dB | +7 dB | not published | -23 dB |
| HiFiMAN Susvara | 60 Ω | 50 mW | +6 dB | +5 dB | not published | -25 dB |
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.
Everything in this paragraph counts only figures the two makers published. An advantage on an axis one of them leaves blank cannot be counted, and is not counted — how often that happens is its own page.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: iBasso DX270 and Lotoo PAW 6000. Or put either against your own headphones in the source comparison tool.
