A simple, no-frills compact design that does its main job successfully; this is yet another superb-sounding Rega stereo amplifier. Why you can trust What Hi-Fi? Our expert team reviews products in ...

Since the ‘80s, ‘90s, with the onset of home theatre, a new term was coined: subwoofer.” Active subwoofers contain their own amplifiers, while passive ones connect to a separate sound system.

Circuit techniques at both the input to the TIA, such as using a resistor or resistor-capacitor or a “dump diode,” and proceeding output gain stages (e.g., time variable gain amplifiers ...

These state-of-the-art amplifiers play a critical role in enabling quantum computers to operate efficiently at extremely low temperatures of 4 Kelvin (-452°F), a prerequisite for high-fidelity ...

Another factor is whether the subwoofer is sealed or ported. Ported models are typically more expensive put performance can be subjective. Ported subwoofers can provide deeper bass, while sealed ...

Headphone users will also appreciate a dedicated headphone amplifier circuit for those moments where you want to escape from it all ... full-bodied sound at lower volumes. There’s a dedicated ...

We’ve been listening to a lot of integrated amplifiers over the past 12 months, and these 4 are some of the best below $3,000. The Ragnarok 2 continues Schiit’s mission of offering American-made ...

a very simple op amp circuit with some detail omitted If you open this circuit in the Falstad simulator, you’ll see two sliders to the right where you can tweak the input voltage. If you make ...
