If you have read about the incredible Stereophile Class A rated DiaLogue Premium power amplifier, you already know that at $3199 it competes firmly with amplifiers costing $10,000 and more while being better built, more flexible, and easier to use.
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. To learn more about power, read Less Power, More Bass. But for customers with speakers that are 86dB efficient 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!
BAD TUBE INDICATOR
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.
If you bought a lesser amplifier, you would pay hundreds to make this upgrade. Easy to identify through their pink color, these premium resistors from Japan are popular with those who rebuild and upgrade their gear. "Modders" love TAKMAN for their low noise, linearity, and musicality.
