What's unique about the brand

Octave is a hifi brand specializing in tube amplifiers that use enhanced pentode configurations to ensure stability with difficult speaker loads down to 2 ohms, while their Super Black Box technology increases power supply capacitance for better dynamics

What reviewers are saying

We read all the reviews. Here's what reviewers feel most strongly about:

  • Octave amplifiers, particularly the Class A models, employ a Dynamic Bias Control system that optimizes Class A operation, extending its benefits of finer, purer sound, while also opening up a wider power range.
  • Octave offers options to increase the power supply capacity of their amplifiers with external "Black Box" or "Super Black Box" capacitor banks, which the company says will improve current delivery, dynamic range, and overall sound quality, particularly when driving difficult speaker loads.
  • These amps allow users to experiment with different power tubes like EL34s, 6550s, KT88s, KT100s, KT120s, or KT150s. The Auto-Bias circuit is a commendably simple controller that lets the user easily optimize the amplifier's settings for each type of power tube.
  • Octave prides itself on the longevity and reliability of its amplifiers, incorporating protection circuits, power management, and soft-start functions, with some models even capable of running safely without a speaker load connected.

Our favorite reviewer quotes:

  • "The V 70's stunning clarity allowed this to happen with the Canton Reference 2s throwing out a huge perfectly defined sound image in Barn that was nearly more space than sounds. With this kind of specific yet billowy presentation, one's attention is drawn well into the intimate workings of every part, every moment, every silence so that time evaporates in the mist of Ana Roxanne's wondrous sound world." (https://twitteringmachines.com/review-octave-audio-v70-class-a-integrated-amplifier)
  • "The strings resonated so naturally, so finely, so effortlessly and at the same time so physically; the whole instrument could be felt in the room. I can't remember ever having heard the work so authentically before." (https://www.lowbeats.de/en/test-octave-v70-class-a-tube-integrated-amplifier-with-a-fine-sound)
  • "Before you think, "Oh, the Octave was hiding the nasties with layers of syrupy distortion," it wasn't, or at least, that's not what I heard. I heard the opposite: an opening up, a growth spurt of harmonic foliage coupled with deep-view transparency." (https://www.stereophile.com/content/octave-audio-v70-class-integrated-amplifier)
  • "Via the V 70 Class A, the "Kraftwerk" classic enchanted us with its airy, spherical sound and its crisp and precise reproduction of impulses. The sounds literally sparkled through our room, the bass came across very contoured." (https://www.enjoythemusic.com/magazine/equipment/1021/OctaveV70IntegratedAmplifierReview.htm)
