Description

PrimaLuna has pioneered numerous technologies to redefine tube amplification. From increased reliability and tube life all the way to their unique, signature sound.

Incomparable Tube Life

PrimaLuna was founded on the idea of eliminating tube maintenance. They do this by using a true and sophisticated Adaptive AutoBias system while running tubes at the minimum dissipation (power) and giving more slam and bandwidth through superior output transformer design.

When It Comes to Bass, Power Means Nothing

It seems everybody is looking for better bass. Especially if they are replacing a tube amp that has no slam, or bass that has poor definition. So they make the mistake of buying more power. Unfortunately, power means nothing when it comes to sound quality, dynamics, and bass slam. An amp can have 200 watts per channel, but if it doesn’t have output transformers with enough bandwidth, the speakers won’t receive it. PrimaLuna is one of only a few manufacturers in the world that actually designs and winds our power and output transformers in-house.

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.

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.

An amp that has “70 watts” will typically give you only 40 watts with Cathode Bias. Most of the power goes up in heat through a single huge resistor. These amps run the tubes very hard. They need to so they can squeeze out the power. That means short tube life and failures via “shorts”.

PrimaLuna’s Adaptive AutoBias is a true, smart technology. It employs 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.

Key Features

  • Headphone Amplifier – One of the best headphone amps in the world. And the only amp that lets you listen with either the warmth of Triode or the wide-bandwidth of Ultra-linear operation at the push of a button!
  • 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.
  • Custom Toroidal Power Transformer – All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever.
  • Custom Super-Wide-Bandwith Output Transformers – Output transformers are the most important part of any tube amp. They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don’t have the bandwidth. PrimaLuna uses lower power to extend tube life, and bandwidth to give you slam.
  • 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. PrimaLuna’s Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time.
  • Point-To-Point Wiring – 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.
  • Superquiet Line Inputs – Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible.
