A single chassis preamplifier with a built-in phono stage and internal power supply

Similar to Linea, this preamplifier uses an extremely short signal path with only one active stage maintained in a simple topology. It is complemented with specially selected parts and a state-of-the-art quality output transformer.

Robustly built, LF2 delivers exceptional sound dynamics and impact at both micro- and macro-levels. The deep, tight, accurate bass adds to the transparent and liquid midrange with a sense of openness and a lack of compression in the upper frequencies. As with all our products, LF2 is hand-assembled and tuned by our team of expert audio artisans. Through this approach, we achieve our main goal and trademark of Viva Audio design: to communicate the original sound, meaning and emotions of a live performance.
