Against the recent used-market anchor of a US$2,873 median and US$2,995 75th percentile, US$4,999 is ambitious and sits well above the usual asking range. That doesn’t make it absurd for a clean, desirable vintage McIntosh piece, but it is priced for a seller who’s expecting strong cosmetic condition, solid service history, or extra collector appeal.
The MC2205 is respected for its big, effortless sound, classic meters, and sturdy build, so a well-kept example can still be a very satisfying buy. The real value hinges on provenance and upkeep: look for documented service, original or correct glass and faceplate, and confirmation that the unit runs cool, quiet, and fully to spec, because at this price the burden is on the listing to prove itself.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
