Not published means the maker leaves it out, so that axis cannot be compared.

Only the Creative Sound Blaster X5 has a separate balanced rating from its maker; through it, it reaches 100 dB on 561 of the 567 models here. The SMSL C200 may still have a balanced socket — its spec sheet simply gives no figure for one, so there is nothing to put beside it. Derived figures are worked out from the loads the maker did publish.
| Load | Creative Sound Blaster X5 | SMSL C200 |
|---|---|---|
| 32 Ω | Derived | Published |
| 150 Ω | Published | Derived |
| 300 Ω | Derived | Derived |
| 600 Ω | Published | Derived |
Both makers publish a power rating. Creative Sound Blaster X5 publishes at 150 Ω and at 600 Ω; SMSL C200 at 32 Ω. The other rows are worked out from those.
So the two columns are not equally firm row by row: at 150 Ω and at 600 Ω only the Creative Sound Blaster X5 figure is the maker’s own and at 32 Ω only the SMSL C200 figure is the maker’s own. On those rows the derived number is the one to doubt first.
6 headphones reach 100 dB on the SMSL C200 but not on the Creative Sound Blaster X5 — Moondrop COSMO, Moondrop PARA, Symphonium Crimson, 3 more.
561 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 Campfire Audio Andromeda 2020: SMSL C200 has +26 dB of headroom there against +9 dB. 16 dB is about 43 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Creative Sound Blaster X5 and SMSL C200 because neither maker publishes no output noise figure.

The Creative Sound Blaster X5 costs $66 more than the SMSL C200, and on these three axes the money buys nothing: among the 567 models here there is not one that the Creative Sound Blaster X5 handles and the SMSL C200 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper SMSL C200 drives 6 models to 100 dB that the Creative Sound Blaster X5 does not.
Only published figures count here; blank axes are counted separately.
