Short answer
Both are desktop amplifiers, $2799 against $3798.
On raw power they are level: each reaches 100 dB on 567 of the 567 non-electrostatic models here.

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

Through the balanced sockets the two are level on the same test: each reaches 100 dB on 567 of the 567 models here. Derived figures are worked out from the loads the maker did publish.
| Load | Burson Soloist 3X GT | Holo Audio Bliss KTE |
|---|---|---|
| 32 Ω | Published | Published |
| 150 Ω | Published | Published |
| 300 Ω | Published | Derived |
| 600 Ω | Derived | Derived |
Both makers publish a power rating. Burson Soloist 3X GT publishes at 32 Ω, at 150 Ω and at 300 Ω; Holo Audio Bliss KTE at 32 Ω and at 150 Ω. The other rows are worked out from those.
So the two columns are not equally firm row by row: at 300 Ω only the Burson Soloist 3X GT figure is the maker’s own. On those rows the derived number is the one to doubt first.
On power they are interchangeable across this whole database: there is no headphone here that one reaches 100 dB on and the other does not.
14 headphones are left alone by the Burson Soloist 3X GT under the one-eighth rule but coloured by the Holo Audio Bliss KTE (64 Audio Nio, 64 Audio Volur, Campfire Audio Andromeda 2023, 11 more).
567 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 Shure SE846: Burson Soloist 3X GT has +48 dB of headroom there against +43 dB. 5 dB is about 3.3 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Burson Soloist 3X GT and Holo Audio Bliss KTE because neither maker publishes no output noise figure.

The Holo Audio Bliss KTE costs $999 more than the Burson Soloist 3X GT, and on these three axes the money buys nothing: among the 567 models here there is not one that the Holo Audio Bliss KTE handles and the Burson Soloist 3X GT does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper Burson Soloist 3X GT leaves 14 models alone under the one-eighth rule that the Holo Audio Bliss KTE does not.
Only published figures count here; blank axes are counted separately.
