Fostex T20
Price trend
21 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
5 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $50 and $59. The full range is tight — lowest to highest is only 1.2×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
What buyers should know
Earpads and headbands are consumables and often need replacement — check whether replacements are still available for the model. On planar and electrostatic designs, confirm the drivers are undamaged, since these are rarely economically repairable.
This range reflects 5 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is enough to establish a working range, but not enough to be precise — treat it as a guide rather than an appraisal.
