McIntosh A150
The McIntosh A150 is an integrated amplifier with very thin documentation, even by the standards of this archive. The record confirms one signature spec: full DC power up to 150 watts into 8 ohms. That phrase shows up on McIntosh's own product page and in period dealer listings, so two independent sources back the one concrete technical fact we have.
Past that, things get murky. One blog source groups the A150 among "McIntosh Anniversary Edition" amplifiers released circa 2000. The official McIntosh listing calls it simply an integrated amplifier, with no anniversary designation, and no production dates are given anywhere. The anniversary claim should be treated with caution. It may be a mix-up with another model from that period.
Here is what we don't have: THD or frequency response figures, dimensions or weight, input and output counts, circuit topology details, and the original price. Period dealer listings and announcements exist, but nothing pins down the A150's place in the lineup or its market timing. Amplifier listings from the period show a range of power and price points, including a 175-watt mono amplifier at $3,500 per pair (HiFI-Stereo, 1995, p.84).
Known specs:
- Integrated amplifier
- Full DC power up to 150W into 8 ohms
- Production era uncertain — possibly circa 2000, unconfirmed
If you own an A150 or have original literature, this page could use your help. The record holds one confirmed spec, one unconfirmed date, and a lot of open questions.
