IFA Berlin 2017 with More Exhibitors and More Innovations Than Ever Before

The International Funkausstellung (or The International Consumer Electronics Show) in Berlin is probably the most important annual event for the consumer electronics industry, introducing new products in time for the most important season of the year for sales. IFA 2016 featured more than 1,800 exhibitors and attracted 240,000 visitors, with the majority of trade visitors coming from outside Germany. The 2016 floor space was already the larger in the show’s history. Expect the 2017 edition to be even larger!...

Amplifier War and Peace - An Hybrid Amp

Amplifier War and Peace - An Hybrid Amp

Simon Brown rethinks what he needs as the amp that will be the centerpiece in his own audio system and perfects a previous design with a true hybrid design. As he writes, "This amp is a “hybrid” in many ways. There is the obvious way in which it uses both valves and MOSFETs. But it’s also a hybrid in its use of enriched Class A/B, which means it is running Class A up to a few watts. This is deliberate." Read the complete project now. This article was originally published in audioXpress, March 2007.

Orange simply says, "it is one of the most musically sounding of its kind on the market today."

The 2A3 Tube Amplifier - A Tribute to Simplicity and Warm Sound

"There is nothing quite like a quality tube amplifier," states the author in the introduction to this directly heated triode amplifier project. The idea for the amplifier started from the author's discovery of the Loftin-White circuit. The author chose the 2A3 directly heated triode power tube to implement the Loftin-White circuit. The 2A3 vacuum tube is a power triode capable of outputting 3.5 W in a single-ended Class A configuration. This article was originally published in audioXpress, August 2013.

Poddwatt Series II Stereo Integrated Valve Amplifier

This article focuses on the Poddwatt Series II stereo integrated valve amplifier, a project with roots that go back several years. The design continues to be relevant and to evolve. I call the basic design an “Oddwatt” because of its “odd” configuration, using two stages. This article was originally published in audioXpress, May 2013.
