Burson Soloist Prime

Class A headphone power amplifier with 12 W via XLR and no volume control


Important: The Soloist Prime has no volume control and no preamp outputs. You control the volume on your DAC, streamer or preamp.

The Soloist Prime is the pure headphone power amplifier of the Voyager series. Burson removed the volume control, preamp stage and display and used the space for a two-level layout: input buffers and IEM stage on top, the dual-mono power stage with MOSFET transistors below. Ten Max Current power supplies feed the unit, twice as many as in the Soloist Voyager. Burson specifies 12 W into 32 Ω and 2 W into 300 Ω via XLR, and two analogue meters show the level instead of a display.

Deluxe or Max

On the Prime, the versions differ more than on the other models:

  • Deluxe: V7 Vivid Pro op-amps, second-generation Silent Power modules, dual-mono IEM stage with TPA6120A2 chips and Super Charger 5 A power supply.
  • Max: adds a discrete Class A IEM stage, the Fusion Core power supply (GaN technology, 24 V, 15 A) and the Burson universal remote control.

Headphones plug into 4-pin XLR, 4.4 mm or 6.3 mm. You activate the IEM stage via the lowest gain setting, and it is not intended for full-size headphones.

What the press says

Passion for Sound

The video review of the Max stayed silent with sensitive IEMs that hissed on the Soloist Voyager. In a direct comparison both sound tonally the same, with the Prime around 5 to 10 % more transparent and better separated. If you need a preamp or do not use IEMs, the review suggests the Soloist Voyager may be the better buy. The unit runs hot, and the meters can hit their end stops with very hard-to-drive headphones.

Who is the Soloist Prime for?

For anyone who owns a DAC or preamp with good volume control and only needs the power stage, from very sensitive IEMs to hard-to-drive planars. If you also want to use the unit with speakers, choose the Soloist Voyager.
