What else to know about the McIntosh MHA 150?

"Once I got over that mental hurdle, I could hear the MHA150 for what it is – a superbly capable source and headphone amplifier. It drives the Meze Empyrean with an authority I only associate with the best in class (at this price point). Transient response, bass texture, imaging, and treble refinement are simply superb - and on a level that I’ve experienced only from the very best headphone amps to grace my review system- the Niimbus US4+, the Pass Labs HPA-1 and the Cayin HA300. Note that those are typically dedicated headphone amplifiers without integrated DACs or speaker-amp functionality, yet their prices aren’t far off from the versatile MHA150. All up, an interesting development that I didn’t anticipate. Five decades down the line and we get the McIntosh MHA150- a marvel of versatility. Its headphone amplifier is more than price-competitive at its US$5000 asking but also gives us an excellent DAC plus a very decent loudspeaker amplifier for an all-in-one solution that demands hard work to find its audible compromises. Minimizing cable clutter and the risk of hardware mismatches, the MHA150 is an easy choice for all but the most difficult to drive headphones and/or demanding speakers in larger rooms. Let’s talk value. The MHA150 is certainly not cheap. Yet when we adjust the MAC1700’s 1969 MSRP of US$599 MSRP for inflation, we get US$4200. That’s not far off the price of the MHA150, despite the new model having a more robust feature set, excellent onboard D/A conversion, increased power in the speaker amp, and a vastly superior headphone output. Now that’s what we call progress!" - Darko.Audio

Brief History of McIntosh

Long mapped-to Binghamton New York – the current headquarters and manufacturing center for McIntosh Labs – not many people know the brand was originally launched outside of the Nation’s Capital in Silver Spring Maryland, in 1949. In 1956, the brand built their original facility in New York, according to the official brand website.
