Both are desktop amplifiers, $2799 against $3000. 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 Burson Soloist 3X GT reaches 100 dB on 567 of the 567 models here, the McIntosh MHA200 on 566.
| Specification | Burson Soloist 3X GT | McIntosh MHA200 |
|---|---|---|
| Power into 32Ω | 4.0 W | 500 mW |
| Power into 150Ω | 650 mW | 475 mW |
| Power into 300Ω | 320 mW | 485 mW |
| Power into 600Ω | 160 mW | 500 mW |
| Output impedance | 0.5 Ω | not published |
| Output noise | 1.5 µV unverified | not published |
| Price | $2799 | $3000 |
| 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 Burson Soloist 3X GT but not on the McIntosh MHA200 — Symphonium Titan.
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: Burson Soloist 3X GT and McIntosh MHA200. Or put either against your own headphones in the source comparison tool.
