PrimaLuna Evo 100 Tube Integrated Amplifier

PrimaLuna Evo 100 Tube Integrated Amplifier – PrimaLuna

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

BAD TUBE INDICATOR

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. (ProLogue Classic illuminates an LED on the front panel.) 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.

CUSTOM TOROIDAL POWER TRANSFORMER

Power transformers generate two types of noise, magnetic and acoustic. That’s why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. 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.

ADAPTIVE AUTOBIAS

PrimaLuna’s Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time. More important, it is the ONLY circuit of its kind that is truly “adaptive” by addressing “tube pinch off” at higher volumes, therefore reducing distortion by over 50% and greatly extending tube life. 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.

NO INTERNAL DAC / NO INTERNAL PHONOSTAGE

Never buy an integrated amp with an internal DAC. Why? Because digital changes, and history shows that integrated amps with “old” digital become unwanted and have almost no resale value. Built in phonostages are “throw in” and are rarely good quality because manufacturers assume 90% of buyers won’t use them. The external phonostage market is very competitive. You can get something much better for as little as $200, and buy one that actually meets your cartridges needs and YOUR budget.
