Orchard Audio’s Starkrimson 25 Mono Premium delivers clean, efficient Class D power with precision and upgrade options for existing owners—no gimmicks, just performance.

Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until now.

Musical Fidelity’s Nu-Vista 600.2 is an all-analogue (no streaming, no DAC), dual mono amplifier offering 160wpc into 8 Ohms and 300wpc into 4 Ohms. It is even 2 Ohm stable.

For analog systems, the field effect transistor (FET) is regarded as one of the fundamental electronic devices. However, its small gain restricts the application of FET in amplifiers and analog ...

It’s slightly more expensive than the competition, but the Bose SoundLink Flex gen 2 justifies its higher price with great sound quality and app connectivity. I think it looks great too, and the ...

In the last years several ultra-low voltage (ULV) operational transconductance amplifiers (OTAs) with supply voltages below 0.5V have been proposed in the literature. To achieve high gain, multi-stage ...

The quasi-lumped impedance transformer and the multiple resonance circuit were designed based on accurate equivalent circuits for internal components inside the packaged transistor. Based on power ...

The $1,699 Schiit Audio Ragnarok 2 Integrated Amplifier plays in the sandbox with some heavy hitters. Does its headphone amplifier make it better?
