Do you have some classic rock albums you used to love so much that have now ended up left on the shelf, un-played for years? How about jazz or classical recordings from the 60’s? Every audiophile has albums that they used to play, but stopped because they are harsh, brittle, or bright. There is a solution.

Triode and Single Ended Triode (SET) amps are popular for their warmer, fuller, and easy to settle into sound. But triode amps have limitations! Ultra-linear has more extension on the top and bottom, not to mention greater power. They have greater “pop” with a bigger difference between light and dark, and loud and soft. Having triode only is VERY limiting.

The best option is to have both triode and ultra-linear. PrimaLuna engineers in Holland designed an ingenious circuit that lets you change from triode to ultra-linear with a push of a button on the supplied remote control. No need to get up and stop the music. Make an instant comparison while you listen and choose what you like best for that song or album.


AC Offset Killer is about goose bumps. The ones you get when music comes out of a background so quiet, you may say to yourself “Just how is this possible?” PrimaLuna custom-winds our own massive toroidal power transformers that are low in hum and EMI. But we wanted more. Our engineers designed the AC Offset Killer to lower transformer noise to a place no other manufacturer dreams of going, regardless of how bad your electricity is. The result? Sense of space. Texture. The resonance of an acoustic guitar or violin string that seems to trail on forever. The AC Offset Killer will amaze you.


PrimaLuna engineers wanted to make owning a tube amp so simple you would have no excuse not to have your tube dreams come true.

If a tube fails, Adaptive AutoBias will instantly put the amplifier into protection mode so no parts can get damaged. A red LED will light up in front of the tube that needs replacing. Simply plug in another tube, and listen. No guesswork. No smoking amp. No getting out the soldering iron or dropping your amp off at UPS.
