Swiss Made Wiring

Swiss Made Wiring
EVO 300 & EVO 400 models use Swiss-made, silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric in the critical signal path for superior signal speed and increased clarity.
   
Takman Resistors
?
Takman Resistors
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.
   
AC Offset Killer

AC Offset Killer - A PrimaLuna Exclusive
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.
   
Triode/Ultra-Linear Switching
?
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.

Adaptive AutoBias
?
Adaptive AutoBias
What most companies call Auto Bias is actually "Cathode Bias"- A commonly used method that is cheap to make, and often found in guitar amps, but also $20,000 high end audio amps. It reduces the available power of the amp and runs the tubes hard, meaning shorter tube life and failures via "shorts".
PrimaLuna's Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time. Adaptive AutoBias is completely passive and NOT in the signal path. The result is low to no maintenance, long tube life, and the lowest possible distortion for amazing sound.
KT150 Compatible
?
KT150 Compatible
In 2006 PrimaLuna introduced the original DiaLogue series; the first amplifiers designed to be as close to being future proof as humanly possible. Back then nobody imagined a tube like the KT120, let alone the KT150, which combines the sweetness of a 300B with bass and control never seen before. Now other companies are scrambling to make a product built to handle the demands of this incredible tube.
EVO 400, 300, & 200 poweramps and integrated amplifiers are built with huge power transformers and filaments supplies needed to run KT150 tubes. And the ingenious design of our exclusive Adaptive AutoBias circuit means that PrimaLuna buyers from ten years ago don’t have to sell off their system to enjoy new tube developments.
Point-to-Point Wiring
?
Point to Point Wiring
You spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?
PrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.
Bad Tube Indicator
?
Bad Tube Indicator
A small LED in front of each power tube lights up if the tube goes bad. The circuit then puts the amp into protection mode. With other brands, this may be when you have to break out the soldering iron to replace a plate resistor, and replace two or four tubes because your amp requires matched sets. With PrimaLuna, you just replace the bad tube (no matched tubes required), and turn the amp back on. No hassles, no headaches.
Wide-Bandwidth Output Transformers
?
Wide-Bandwidth Output Transformers
250 watts of power will have no top and bottom extension if the transformers don't have enough bandwidth. We use lower power to extend tube life, and bandwidth to give you slam. Our output transformers are custom wound in-house for deep and tight bass extension, an extended top without even a hint of grain, and our famous PrimaLuna midrange.

Toroidal Power Transformers
?
Custom Potted Toroidal Power Transformers
Unlike standard EI transformers, toroidal transformers don’t radiate a magnetic field, which can is easily detected in preamp circuits as low-level "hash". Although expensive to manufacture, PrimaLuna power transformers are built huge and rated for 200% of their duty cycle. PrimaLuna transformers are also potted and enclosed to protect the windings from moisture and deterioration forever.

SCR Tinfoil Capacitors
Made in France, these capacitors are used in the critical signal paths and while they are expensive, the PrimaLuna team felt they could not be left out after careful listening comparisons with many different types.
