To be able to listen to turntables through your system, you'll need a phono stage (also called a phono preamp). These are the best models we've reviewed across all budgets and types.

Want the ultimate audiophile sound quality from your vinyl records and have an infinite budget? These high-end turntables are worth considering.

Planar multibeam vacuum electron devices (VEDs) offer enhanced output power in the terahertz (THz) band by increasing total beam current while maintaining appropriate current density. Their associated ...

In this paper, we propose a novel design of GaN-based planar Gunn oscillator as terahertz signal source. The oscillator has multiple gates and each gate can be individually biased. By controlling gate ...

Surface-enhanced Raman scattering (SERS) has demonstrated remarkable potential for molecular detection due to its specificity. However, detecting fluorescent vitamin B molecules remains challenging ...
