About the Vali 2++
The Vali 2++ is a compact hybrid headphone amplifier and preamplifier using a single user-replaceable 6N3P tube for voltage gain and a discrete solid-state output stage. It has switchable high and low gain, one pair of RCA inputs, variable RCA preamp outputs, and a 1/4-inch headphone output. The preamp outputs are muted when headphones are connected. Its supplied power supply provides regulated rails for the tube and solid-state circuitry.
