XACT S1 Music Server


The brochure included with the XACT S1 music server hammered on the point again and again. Digital that doesn't sound like digital. More like vinyl. The single-minded focus caused me to reflect on the scene and our recent history. What began with Perfect Sound Forever in 1983 is now snubbed in 2024. The new standard... Read More »


Music Streaming with Fidelizer - the Nimitra2 Server + Nikola2 LPS + EtherStream Network Switch


When something is not as advertised, I have no problem calling it out. So it was when music streaming came along.

Advanced Optical Streaming with the Sonore Signature Rendu SE System Optique


Since Adrian Lebena reached out to me three years ago with the offer to review Sonore's first product, the microRendu, a Sonore streamer has been in my system ever since. The microRendu was amazing—especially when paired with Sonore's Signature Linear Power Supply. It took my streaming experience—which previously had been restricted to bandwidth-limited and feature-limited... Read More »

Fidata HFAS1-XS20U Network Server/Audio Files Transport


Before our eyes, slowly a hierarchy of devices used to play audio files begins take a shape.
