No transformer or capacitors interrupt the audio signal path — it’s pure tube power. According to the brand, this “extremely uncommon topology is usually reserved only for cost-no-object designs.” The ...

Its best known for high-end, spherically-shaped loudspeakers, but the brand makes a variety of other audio components, too, including turntables and amplifiers. Its latest amplifier, the Connect 2130 ...

There’s a mystique among both audiophiles and musicians about vacuum technology, thus having a tube amp still carries a ... it’s not for audiophiles. The circuit is a pretty conventional ...

Like Folkvangr, the Schiit Valhalla 3 operates as a OTL/OCL design—no output transformers, no capacitors in the signal path. Translation: your headphones are getting raw tube power straight from the ...

Here is the introduction, and 2 of 5 schematics: An audio pre-amplifier is meant to drive a power amplifier and does provide the controls, the knobs. This Pre-Amplifier circuit is a minimalistic ...
