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.
This is the ANNOUNCEMENT date, not a release date. Astell&Kern unveiled the PD5 on August 3, 2026 (https://www.forbes[3].com/sites/marksparrow/2026/08/03/astellkerns-pd5-player-boasts-day-long-battery-and-eight-dac-design/ and https://www.whathifi[2].com/hi-fi/portable-music-players/the-astell-and-kern-pd5-digital-audio-player-follows-the-award-winning-sr35-with-a-28-hour-battery-life-and-eight-dacs), ahead of its public debut at the Hong Kong High End AV Show on August 7-9, 2026, and explicitly did not announce pricing or availability, saying those details would follow 'soon'. No source found states when the PD5 actually went on sale, so the announcement day stands in and the confidence is unknown.
What Hi-Fi's own headline, dated 3 August 2026, describes the Astell & Kern PD5's 28-hour battery and eight-DAC design, predating the pin's stored 8 September 2026 roundup date by about five weeks; the page itself could not be fetched to quote directly.
Forbes' own headline, also dated 3 August 2026, corroborates the PD5's day-long battery and eight-DAC design, again predating the pin's stored 8 September 2026 date by about five weeks; the page itself could not be fetched to quote directly.
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.
