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.
Availability is given only as a month: HiFi Pig's[3] launch report (https://www.hifipig.com/michi-prestige-p430-pre-amplifier-and-michi-prestige-s430-stereo-power-amplifier/) says the Michi Prestige S430 is 'available from September 2026', with no on-sale day stated anywhere. Dated to the last day of that month, 30 September 2026, as an estimate.
Gear Patrol states "Both of Rotel's[1] new Michi Prestige components... will be available this month," published 7 September 2026, a day before the pin's stored date, matching its "already available" framing.
HiFi Pig states the amplifier "will be available from September 2026," published 2 September 2026, consistent with the pin's stored 8 September date within the same month.
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.
