If you need to drive some speakers with really good audio, you have some really good choices these days. Tripath, in San Jose, CA, was the first to introduce a Class-D amplifier chip, the TA1101, in ...

Love Class A amplification but hate the heat associated with it? The Infigo Audio Method 6 offers a very different take. There are many ways to eat your Smarties and Infigo Audio believes that it has ...

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 ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

Say Konnichiwa to the N-05XE streaming DAC/pre-amplifier and headphone amplifier and the S-05XE Class A power amplifier.

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 ...

In market for a powerful 200 WPC amp? ATI has you covered with two completely different technologies. We compare the AT4000 class A/B and the AT522NC Class-D amplifiers to help you decide. EIA 1kHz ...
