Corvina LFP-V Edition (Discontinued)

Headphone Amplifier

Audiophile sound quality. ‘Budget-friendly’ pricing. Can be ordered with single-end or optional balanced output stage.


Corvina is the same headphone amplifier found in our flagship Isabellina HPA, but with less features and more economical packaging. Corvina is ideal if you already own a DAC and don’t want to break your budget.

  • Two switchable inputs
  • Alps Blue Velvet volume control *
  • Optional 4-pin XLR balanced output stage
  • Delivers a highly-resolved and seductive headphone listening experience
  • Couples warmth and tone, while uncovering subtle details and delicate spatial cues
  • Runs on pure LFP battery power, so Corvina can be easily transported to the patio or work
  • Like all our products, Corvina is hand-built in the USA

* Does not support remote volume control

Take your entire headphone system off-the-grid!

Optional 5V/12Vdc output jack allows you to take select products like Wadia i170, Onkyo ND-S1, Pure  i20 and others off AC power, letting you harness the benefits of LFP battery-power for your entire headphone rig.

*Custom-made DC power cable sold separately
