Generation & platform

The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?

Same generation

The STAX SR-007S is 2 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price.

What reviewers said

Abyss Diana V3 MR

The Abyss Diana V3 MR is a premium wired over-ear headphone featuring a 63mm planar magnetic driver, delivering a smooth, transparent, and well-balanced sound with strong detail and immersive imaging. It offers a fuller, more accessible tuning compared to earlier Diana models, though it still benefits from a capable amplifier despite its moderate 30-ohm impedance. Build quality is high, but comfort is only average due to limited padding, and the proprietary cable may be a consideration for some users.

  • Pro:Smooth, balanced, and engaging sound signature
  • Pro:Strong treble extension and immersive imaging
  • Pro:Powerful bass and rich mids for a complete presentation
  • Con:Comfort is average; padding could be more generous
  • Con:Requires a capable source for optimal performance
  • Con:Proprietary cable limits aftermarket options

STAX SR-007S

The STAX SR-007S is a refined electrostatic flagship that builds on the classic Stax formula with updated internals and comfort-focused earpads. It delivers a spacious, highly detailed soundstage with warm bass and clear treble, all while maintaining a smooth, airy presentation. This wired, over-ear design is a perfectionist's choice for those seeking an evolutionary upgrade in high-end audio.

  • Pro:Spacious and precise soundstage
  • Pro:Warm, deep bass with clear highs
  • Pro:Improved comfort and reduced earcup resonance
  • Con:Requires a dedicated electrostatic amplifier
  • Con:Very high impedance limits portability
  • Con:No built-in controls or wireless features
