The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
On-sale date: FiiO started EA13 sales in mainland China, online and offline, at 10:00 Beijing time on 27 July 2026 (https://mychooz.com/en/news/new-fiio-ea13-144060). International stock followed in August; FiiO's own release page says only 'available now'.
What Hi-Fi's own headline confirms the FiiO EA13's "retro-modern" 1950s-tube-amplifier styling, supporting the pin's description, though the fetched page returned only navigation content and no publish date is stored to compare against the pin's date.
Darko Audio's own review title, "Party like it's 1959: FiiO EA13 review," carries a stored publish date of 1 August 2026, about five weeks before the pin's stored 8 September date, consistent with a review appearing ahead of the item's inclusion in a later gear roundup; a 403 error blocked retrieval of the text.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
