The MC1502 Vacuum Tube Amplifier is a stereo amplifier designed for home audio and home music systems that produces 150 Watts per channel. It is the direct replacement to our award winning MC2152 Limited Edition 70th Anniversary Vacuum Tube Amplifier, which was released in celebration of our 70th Anniversary that occurred in 2019. The new MC1502 has identical audio specifications and sound reproduction performance of the heralded MC2152 but in a more customary McIntosh design.

The MC1502 "combines brutal control and quantities of power, with openness and sophistication. The amplifier is potent enough to power most speakers, and will only sound better the more it has to work with." Highly recommended. – Lyd & Bilde

The MC1502 shares the timeless styling of our classic MC275 Vacuum Tube Amplifier. As the MC1502 has twice the stereo power rating of the MC275 (150 Watts vs. 75 Watts) and is physically larger, in many ways it can be considered the MC275's big brother. And while a pair of MC275s can be run in mono to achieve the 150 Watts per channel output of the MC1502, the MC1502 boasts a better signal-to-noise ratio of 112dB vs. 105dB for the MC275 pairing – producing an even quieter performance than the already quiet MC275.

The MC1502 is "an unqualified hit." It has the "cleanliness, low noise, and bandwidth of the best sounding modern amp designs with just enough of the special sauce that I love about tubes and transformers. True high-end audiophile sound in all its refined glory, without any rare tube types, finicky setup, or usage idiosyncrasies. Plus, LOTS of power and some fun features all in a beautiful package built to last a lifetime and beyond. Highly recommended." – Part-Time Audiophile

The MC1502 is powered by eight KT88 output vacuum tubes, with four assigned to each stereo channel. It also has eight small signal tubes, consisting of four 12AX7A and four 12AT7 vacuum tubes; two of each of these vacuum tubes are dedicated to each audio channel. The 12AX7A vacuum tubes are for the Balanced and Input amps, while the 12AT7 tubes are for the Voltage and Driver amps. All the vacuum tubes are covered by a 12-gauge stainless steel wire cage with a black powder coated finish.

The MC1502 Vacuum Tube Amplifier and C22 Vacuum Tube Preamplifier Mk V represents McIntosh’s traditional heritage sound and with the added modern McIntosh technology, another masterpiece is born. – HiFi & Home Theater Audio

The KT88 vacuum tube sockets include Air-Pipe cooling at their bases to help facilitate long service life. The eight signal tube sockets have ceramic base construction with gold plated contacts, providing protection from atmospheric contamination. All the vacuum tubes sit atop the precision formed stainless steel chassis polished to a mirror finish. Our Sentry Monitor™ technology monitors the output current and shuts the amplifier off if it ever exceeds safe limits; the signal tubes will flash red if Sentry Monitor is ever activated.

The MC1502 Vacuum Tube Amplifier and C22 Vacuum Tube Preamplifier Mk V is "outstanding equipment" and "is rich with an uncommon magic and will provide precious pleasure. Moreover it will fit most loudspeakers nicely, even the most demanding ones." - Haute Fidélité

Unlike many other amplifiers, the MC1502's full 150 Watts can be delivered to almost any pair of speakers regardless if they have 2, 4 or 8 Ohm impedance. This is thanks to our patented Unity Coupled Circuit output transformer technology – the same technology McIntosh was founded on in 1949. Two Unity Coupled Circuit output transformers flank the power transformer which is positioned between them. Each transformer is housed in a glass topped extruded enclosure that displays the wiring diagram for each transformer. Two fully spelled out vintage die cast aluminum name badges adorn two sides of the MC1502, while an abbreviated badge is centered between the Tube Lights and Power knobs. 

"Extended listening reveals that this amplifier is just as good at low volumes as it is pushed to its limit... In addition to sounding great at high and low volumes, the MC1502 handles the most densely packed and technically challenging recordings with ease... this amplifier is quiet. There are plenty of solid-state amplifiers that aren’t this quiet... Tube amplifiers aren’t for everyone, but the McIntosh has gone above and beyond expectation to bring us an amplifier that produces plenty of power, sounds fantastic, and is well built... The highest compliment I can give the MC1502 is that I’m selling my beloved MC275 and buying a rack with a bigger lower shelf. It’s a keeper." - Tone Audio

Both balanced and unbalanced inputs are included to connect the MC1502 to your preamplifier and the rest of your home audio system. Our patented Solid Cinch™ speaker binding posts will securely connect your speaker cables to your speakers.

An input and output for our Power Control technology allows other connected McIntosh components, such as preamplifiers, CD players, turntables, or media steamers, to automatically turn on and off.
