Triple X-rated – That's Burson's newest Soloist 3X Performance [$1'144] headphone preamp. It outputs a colossal 8/4wpc on XLR/RCA respectively and runs the Japanese Muse 72320 chip-based precision attenuator like flagship preamps from Pass and AVM. Three levels of feedback-adjusted gain are said to match headphones from 60-110dB sensitivity. The gain circuitry is class A, the discrete opamps are socketed to allow rolling and there's even headphone power-amp mode to bypass the volume control.
