Does the Mercury/Solis pairing tick all the boxes?

As audio/video hobbyists, most of us grew up thinking that if we have an amplifier with 50 watts of rated output power into 8-ohm speakers, and that combination produces reasonably clean and loud ...

Unison Research’s Unico PRE v2 and DM v2 introduce a modern design, substantially more power, and an $18,498 system price—no streamer, no Bluetooth, just intent.

Let's assign a point system to determine if you may benefit from an external amplifier, or if you would be better served by saving your cash. Please keep in mind this is not a biblical source. I ...

The process of designing traditional fixed-supplypower amplifiers has been well-establishedfor many years. Well-definedmetrics for performance assessment exist,and the amplifier designer’s job is to ...

Specifying the power supply requirements for audio amplifiers can be tricky. If the power supply is overdesigned it will add unnecessary cost to the product, and if it supply is underdesigned the ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

This article was originally fairly superficial and frivolous, but has been expanded (a little) to explain the matter better. Amplifier power ratings are usually honest in Hi-Fi equipment, but become ...

The need for high power in the VHF, UHF, and microwave bands has led to transistors that can easily supply tens to hundreds of watts at RF frequencies to 10 GHz and beyond. Most of these devices are ...
