McIntosh C100A

Name: McIntosh C100A
Brand: McIntosh

Documentation on the McIntosh C100A is thin. Here is what the record shows. It was a preamplifier with a dual-chassis design - the unit splits physically into top and bottom sections weighing 11.0 kg and 8.7 kg. The two-piece construction was meant to minimize signal interference, and a Japanese dealer's description says it gives "clear and accurate sound quality" as a result. The same source credits it with high-precision volume control and flexible input switching, and calls it a blend of classic McIntosh styling with modern functionality.

Beyond that, almost nothing is verified. No production years, no original retail price, no frequency response or THD figures, and no input/output counts survive in the sources. A single Russian classified listing asks 390,000 rubles for one. Japanese audio dealers have handled the unit for purchase and trade-in, but no owner reviews or long-term reliability notes have surfaced. The C100A appears related to the C100 - a separate page for the C200 references the "dual chassis adopted in the C100" - but no lineup positioning or family hierarchy is established.

What can be said with confidence: it's a substantial, two-piece McIntosh preamplifier, built to isolate sensitive circuitry from interference.
