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.
StereoNET[2] (https://www.stereonet.com/news/mcintosh-cs7500-preamp-streams-its-way-in-as-your-high-end-hi-fi-hub) reports the CS7500 as 'available from 28th August' 2026, two days after McIntosh's 26 August announcement. That stated on-sale day is used as the pin date.
StereoNET confirms the CS7500 became "available from 28th August" (2026) at £14,000, predating the pin's stored 8 September 2026 date by about two weeks.
WebFetch could not retrieve The Absolute Sound's page (403 Forbidden); its title and coverage of the preamplifier's introduction are consistent with the product's launch window around the pin's stored 8 September 2026 date, though unverified 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.
