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 ...

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. Class A – refers to an output stage where the bias ...

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 ...

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 ...

The Platina Stream, developed alongside the Integrated, brings Quad’s legacy into the streaming era with flagship ESS Sabre DAC architecture , precision clocking, and isolated digital and analog ...

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 ...

After five years of development and numerous hi-fi show teasers, Quad has announced the first member of its new Platina ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

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 ...

Over the years there have been many different audio amplifier designs which have found favour for a while and then been supplanted by newer ideas. One of them has crossed the bench of [Jazzy Jane], it ...
