Only the Schiit Ragnarok 2 has a separate balanced rating from its maker; through it, it reaches 100 dB on 567 of the 567 models here. The SPL Phonitor se 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.

| 32 Ω | Published | Published |
| 150 Ω | Derived | Derived |
| 300 Ω | Derived | Derived |
| 600 Ω | Derived | Derived |
Both makers publish a power rating. Schiit Ragnarok 2 publishes at 32 Ω; SPL Phonitor se 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 Schiit Ragnarok 2 but not on the SPL Phonitor se — Symphonium Titan.
566 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 Sennheiser HD 600: SPL Phonitor se has +28 dB of headroom there against +20 dB. 8 dB is about 6.7 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Schiit Ragnarok 2 because that maker publishes no output noise figure.

The SPL Phonitor se costs $101 more than the Schiit Ragnarok 2, and on these three axes the money buys nothing: among the 567 models here there is not one that the SPL Phonitor se handles and the Schiit Ragnarok 2 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper Schiit Ragnarok 2 drives one model to 100 dB that the SPL Phonitor se does not.
Only published figures count here; blank axes are counted separately.
