Welcome to the least expensive serious tube hybrid amp on the planet. Vali delivers solid power into headphones from 32 to 600 ohms. It's a great way to get a taste of exceptional tube sound, for only a tiny investment.
Tubes: Not Just for Show
Some inexpensive tube amps have tubes that aren’t good for much other than show. Not Vali. The 6088 subminiature tubes are triode-connected and provide all the voltage gain. They’re run off a regulated 60V rail, which is optimal for a tube with a 67.5V maximum plate rating. In addition, we're using a regulated 1.2V DC heater, for lower noise, more stable operation, and long life.
Solid Power Output
At the same time, Vali’s tubes are coupled to a solid Class AB output stage that can deliver 650mW per channel into 32 ohms. The result is an amplifier that can drive many different kinds of headphones, including some hard-to-drive orthodynamics. And, it has plenty of voltage output for high-impedance headphones.
Just getting into tubes? Be aware of microphonics. Many small tubes, including the ones in Vali, are microphonic. When you plug in headphones, you'll hear a little "tiiinnnnggg...." noise that takes quite a while to go away. If you rap the chassis, it will do the same thing.
Made in USA
By “made in USA,” we mean made in USA. The vast majority of the total production cost of Vali—chassis, boards, assembly, etc—goes to US companies manufacturing in the US.
