The Dunu DK3001 BD is 26Ω at 108.0 dB/mW; the Dunu SA6 MKII is 24Ω at 114.0 dB (no reference unit printed). This page covers what they ask of an amplifier, not how they sound.
The DK3001 BD needs 6.0 dB more than the SA6 MKII to reach the same loudness — 0.16 mW against 0.04 mW.

One caution before reading the rows. Dunu SA6 MKII printed a decibel figure with no reference unit, so this page reads it as per milliwatt. If it is really per volt, that model needs far more than the table says. Why the two readings differ by so much.
Every source in the database that drives one of them drives the other. On power, the choice between these two changes nothing about what amplifier you need.
21 sources stay below the audible-hiss threshold with the DK3001 BD but cross it with the SA6 MKII (Fosi Audio SK02, FiiO K7, Lake People G103-S Mk II, 18 more).
280 of the 280 sources here reach 100 dB on both.
The DK3001 BD is more demanding than 19% of the 567 non-electrostatic models in this database; the SA6 MKII than 3%.

| Source | Price | Headroom, DK3001 BD | Headroom, SA6 MKII | Output impedance | Noise |
|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 21.9 dB | 27.5 dB | 0.5 Ω | 1.7 µV |
| FiiO KA11 | $29 | 31.2 dB | 37.3 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 28.1 dB | 34.2 dB | 0.6 Ω | 1.0 µV |
Of the 280 sources here, 280 reach 100 dB on both. 47 of them also publish an output impedance low enough for both under the one-eighth rule and a noise figure that stays below the audible-hiss threshold with both.
The cheapest of the 47 is the JadeAudio JA11, at $20. It leaves 21.9 dB of headroom on the DK3001 BD and 27.5 dB on the SA6 MKII, its output impedance is 0.5 Ω against a one-eighth limit of 3.25 Ω and 3.00 Ω, and its noise figure puts the hiss floor 12 dB and 5 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
| Model | As printed | Tolerance | Standard |
|---|---|---|---|
| DK3001 BD | 5 Hz - 40 kHz | not printed | not printed |
| SA6 MKII | 5 Hz - 40 kHz | not printed | not printed |
Dunu prints the same thing for both the DK3001 BD and the SA6 MKII: 5 Hz - 40 kHz.
Neither range has a tolerance printed beside it, so the matching numbers say little.
Not a measurement; maker by maker.
Both have a page of their own. In full: Dunu DK3001 BD and Dunu SA6 MKII. Each figure on this page is labelled on those pages with where it came from, including the ones Dunu never published — what that maker publishes, counted.
