PrimaLuna DiaLogue Premium HP Amplifier

MORE POWER, NOT MORE HASSLES

All PrimaLuna's have incredible slam because of bandwidth. Power is secondary, and can in fact be bad news for unwary customers. But for customers with speakers that are medium efficient with 86dB or lower, that have larger rooms and play at higher volumes, they may need more power. 

The cheap way to get more power from a tube amp is to raise the tube's plate and screen voltage, and bias them harder. It costs nothing to do so as a manufacturer, but we refuse to follow the pack. You will see claims of as high as 100 watts from a pair of KT120's. Initially, the customer is happy. But talk to the same customer in a year when his tubes are worn out. PrimaLuna amps are famous for long tube life, running cool, and being absolutely the easiest amplifier to own. 

The best way to add power and keep running cool is an bigger build. We increased the size of the power transformer, added all the supporting circuitry including tube sockets, Swiss silver-plated OFC wiring, Takman resistors, SCR Tinfoil caps and a second Adaptive AutoBias board. And of course, four more EL34's for unrelenting power. And if you want the ultimate, add a second HP later and flip the switches to mono. Incredible!

REMOTE CONTROLLED TRIODE/ULTRA-LINEAR SWITCHING

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.
