Fostex T40RP Mk3 vs Sivga Anser

Why pick the Fostex T40RP Mk3: This closed back planar magnetic model measures smoothly in oratory1990’s test, with only 2.57 dB of deviation around the target and sub-bass within 6 dB down to 20 Hz. The tradeoff: Sensitivity of 91 dB/mW is low for an over-ear, so a dedicated headphone amp helps it reach full volume.

Why pick the Sivga Anser: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
