Both are desktop amplifiers, $3798 against $3200. 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 Holo Audio Bliss KTE reaches 100 dB on 567 of the 567 models here, the SPL Phonitor x on 566.
| Specification | Holo Audio Bliss KTE | SPL Phonitor x |
|---|---|---|
| Power into 32Ω | 3.0 W | 1.0 W |
| Power into 150Ω | 600 mW | 3.1 W |
| Power into 300Ω | 300 mW | 4.2 W |
| Power into 600Ω | 150 mW | 2.1 W |
| Output impedance | 1.0 Ω | 0.18 Ω |
| Output noise | not published | 5.48 µV |
| Price | $3798 | $3200 |
| Headphones it reaches 100 dB on out of 567 | 567 | 566 |
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.
1 headphone reaches 100 dB on the Holo Audio Bliss KTE but not on the SPL Phonitor x — Symphonium Titan.
15 headphones are left alone by the SPL Phonitor x under the one-eighth rule but coloured by the Holo Audio Bliss KTE (64 Audio Nio, 64 Audio Volur, Campfire Audio Andromeda 2023, 12 more).
566 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.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: Holo Audio Bliss KTE and SPL Phonitor x. Or put either against your own headphones in the source comparison tool.
