Besides the many benefits regarding sound, an amplifier running in pure Class A mode gets very hot!
To ensure a long lifespan for the electronics and a stable running amp, is a true challenge for the designer. That is why most Class A amplifiers come with huge heat sinks, which in many cases still get very hot and are unappealing to look at. For the LaScala PowerAmp the design goal was to use smarter solutions to reduce the heat from the amp.
The pictures above show a row of four heat pipes, including temperature controlled fans mounted from the underside, and four massive heat sinks mounted on top of the MOSFETs. Looking at the LaScala PowerAmp from the outside, only the heat sinks on top are visible. The elegant style of the cabinet gives no sign that a massive Class A amp is working “under the hood”!
Following below are two pictures showing one of four heat pipes, which cool each of power MOSFETs.
The first picture shows the top side of the heat pipe showing the area where the MOSFET is glued to.
The second picture shows the bottom side of the heat pipe with its many narrow fins for effective heat dissipation.
The third shows the low Speed Fans for the Air Circulation. The amplifier can work also with the fans powered off by setting the related parameter at the menu. The fans let only the air moves around the heatsinks. It increases the chimney effect.
With fans excluded the LaScala PowerAmp works at 15°C higher temperature with a reservoir left of 35°C.
With the LaScala PowerAmp, CanEVER Audio has once again proven its skills in offering extremely innovative products to the world of high-end audio. Thanks to the ability to combine well-known and proven engineering concepts with innovative ideas, CanEVER Audio has been able to create a product with amazing sound quality, which is able to compete with the best amps on the market today.
