If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

Krell announced the most revolutionary design change in its 33-year history: iBias, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less ...

Krell announced their new iBias technology at CES 2014 to be integrated into their amplifier line. Many audiophiles (and people that care about sound if you feel "audiophile" is a dirty word) believe ...

Although Class A cost the most and are least practical, they are still preferred because the sound best, returns very clean signal, it is the most linear and has the lowest distortion. The circuit’s ...

The design of the circuit is based on the operation of a class A amplifier for the purpose of driving a pair of headphones using a mini amplifier. The design of the circuit is based on the operation ...

In March 1985, I was reading a copy of my favorite hi-fi magazine. It carried a story about a brand-new British amplifier from Musical Fidelity. The reviews for the A1 amplifier were glowing, as was ...

I am looking at building a ~80W class A amp for experiance and to save costs. I am looking at the AE Aegis One's (nice kit for about $500 here) to couple it with for now but eventually will go up to ...

“Class” is in session. This discussion of electronic amplifier circuits offers an overview of the characteristics that define commonly used class designations ...

Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of analog-to-digital converters (ADCs), they reshape signals from sources as diverse as ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...
