Product Highlights

The Audio by Van Alstine Ultravalve is a pure vacuum tube power amplifier delivering 35 watts per channel into 8 ohms. Operating as a refined anchor for high-performance stereo setups, this component drives high-efficiency loudspeakers with poise and dynamic agility. Built around an evolved Dynaco ST-70 circuit, it features EL34 output tubes, 6GH8A driver tubes, and a 5AR4 tube rectifier. Key engineering upgrades include individual regulated power supplies for each tube stage to eliminate cross-talk, a double-sided ground-plane circuit board, and custom output transformers that broaden frequency response while preserving total signal purity.

Critical consensus from outlets like The Absolute Sound celebrates its authoritative bass control, natural midrange clarity, and vast soundstage presentation. Reviewers applaud its ability to transcend typical vintage tube limitations by rendering rapid dynamic shifts without softening low frequencies. Earned accolades and enthusiast praise continually position it as a benchmark for musicality and spatial resolution in modern tube amplification.

Adding this power amplifier to your system unites classic thermionic character with modern electronic design. Its clean power delivery unlocks subtle details in every recording while maintaining a natural, fatigue-free tonal balance. For those seeking an immersive listening experience with tangible depth, this component provides an enduring foundation for daily musical enjoyment.
