Modding Potential

The SR325i continued the legacy of the original SR325 by incorporating design and acoustic improvements aimed at delivering a more refined listening experience.

  • "i" Series      Enhancements:     The SR325i featured a thicker cable, redesigned aluminum housings, and      improved driver tuning to reduce resonance and enhance clarity.

  • SR325is Variant: Released shortly after the      SR325i, the SR325is offered minor refinements, including subtle tuning      adjustments and improved finishing, making it a collector’s favorite.

  • Legacy: As the flagship of the      Prestige Series, the SR325i remained a standout model, eventually      succeeded by the SR325e in 2014.

The SR325i set itself apart from other Prestige models with its premium materials and unique aesthetic.

  • Materials: Precision-machined aluminum      housings, providing enhanced rigidity and resonance control compared to      plastic models in the lineup.

  • Headband: Leatherette-covered metal      band, offering flexibility and a comfortable fit for most users.

  • Cable: Thicker fixed Y-cable with      UHPLC copper wiring, designed for durability and optimal signal      transmission.

The aluminum housings added weight to the SR325i, which some listeners appreciated for its premium feel but others found less comfortable during extended listening sessions.

The SR325i delivered a highly detailed and precise sound signature, making it a favorite for critical listening and analytical audiophiles.

  • Bass: Tight and well-controlled,      providing a solid foundation without overshadowing other frequencies.

  • Mids: Forward and revealing,      delivering exceptional clarity and detail for vocals and instruments.

  • Treble: Crisp and extended, with a      lively sparkle that added energy to recordings, though it could lean      bright for treble-sensitive listeners.

  • Soundstage: Intimate yet precise, with      excellent imaging and separation that allowed every element in a track to      shine.

The SR325i excelled in genres like rock, acoustic, and classical, where its dynamic and energetic presentation shone.

The SR325i’s unique aluminum housings made it a more challenging modding candidate compared to plastic Prestige models, but it still attracted enthusiasts looking to tailor its comfort and performance.

  • Common      Mods:

    • Replacing ear pads with G-Cush       or Nyczaj Earpads to improve comfort and soundstage.

    • Upgrading the headband for       additional padding, especially for extended sessions.

    • Re-cabling for modern       connectors or balanced audio setups, though this required careful       handling due to the premium construction.

Collectibility and Reception

The SR325i remains one of the most celebrated models in the Prestige Series, known for its unique design and high-performance sound.

  • Community      Reception:

    • Widely praised for its precise       and analytical sound, the SR325i earned a loyal following among       audiophiles who valued clarity and detail.

    • Some listeners found the       aluminum housings and tuning to be slightly fatiguing during long       listening sessions, but many appreciated its unique character.

  • Rarity:

    • The SR325is variant, with its       subtle improvements and limited availability, is particularly sought       after by collectors.

The Grado SR325i stands as a testament to Grado’s ability to innovate and refine its offerings while maintaining its signature sound and design philosophy. As the pinnacle of the Prestige Series during its time, the SR325i remains a beloved model for its precision, clarity, and distinct aesthetic. Whether as a tool for critical listening or a collector’s item, the SR325i continues to captivate Grado enthusiasts worldwide.
