This 50 year old amp looks and sounds like it just came out of the factory box. Troublesome on/off volume control potentiometer has been changed with a new one, purchased from Mcintosh/New York.Refinished wood cabinet brand new glass faceplate and bezel. Oh, and the sound is incredible.
What matters most here: are you getting a clean MA6100 at a price that still leaves some room for its age? At US$1,750, this sits above the median of US$1,584 and even above the 75th percentile of US$1,925? No — it’s still below that upper quartile, so this reads as reasonable-to-firm rather than cheap, but not out of line for a desirable example.
That makes sense for a McIntosh piece: the MA6100 is well regarded for its muscular, full-bodied sound and straightforward integrated-amp appeal, with real long-term collector interest. If it’s original, quiet, and unmolested, the upside is a classic that can anchor a system for years; just verify service history, knob/switch behavior, and whether any needed maintenance has already been handled, because age matters more than cosmetics on these.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
