McIntosh is gearing up to celebrate its 70th anniversary next year. In recognition of its founding by Frank McIntosh, a.k.a. “Mr Mac”, in 1949, the company has announced a unique 70th Anniversary Limited Edition Commemorative System.

The Commemorative System is comprised of two new audio products: the MC2152 70th Anniversary Vacuum Tube Amplifier and the C70 70th Anniversary Vacuum Tube Preamplifier. All the products in each Commemorative System are specially marked and have matching serial numbers.

Additionally, a “…for the love of music…” McIntosh History Book is also included that contains a certificate authenticating the entire system.

Furthermore, only 70 Commemorative Systems are being produced, making each a true collector's item.

For each of the Limited Edition Commemorative Systems sold, McIntosh will donate $1,000 to global humanitarian organisation Save the Children. Founded in 1919, Save the Children will also mark a milestone anniversary in 2019 with the celebration of its centennial.

MC2152 70th Anniversary Vacuum Tube Amplifier

McIntosh MC2152

The MC2152 70th Anniversary Vacuum Tube Amplifier is a 150 Watt per channel stereo amplifier featuring a striking new design in honour of the brand's seven decades of handcrafting what they consider to be the best home audio equipment the world has ever heard.

Utilising their patented Unity Coupled Circuit output transformer technology – the same technology the company was founded on in 1949 – the full 150 Watts can be delivered to almost any pair of speakers regardless if they have 2, 4 or 8 Ohm impedance.

The new design of the MC2152 is highlighted by a bead blasted black anodised aluminium chassis accentuated with matte finish carbon fibre side panels. The front panel showcases a backlit laser cut McIntosh logo flanked by classic McIntosh knobs. The vacuum tubes are covered by a 12-gauge stainless steel wire cage with a black powder coated finish. At the rear, you will find two Unity Coupled Output Transformers with the power transformer centred between them. All three transformers are housed in glass-topped extruded enclosures displaying the wiring diagram for each transformer. A 70th Anniversary badge is laser-engraved into the top plate of the enclosures.

The MC2152 uses eight KT88 output vacuum tubes plus eight small signal tubes comprised of four 12AX7A and four 12AT7 vacuum tubes; half of the tube complement is assigned 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.

The LEDs under the eight small signal tubes can be set to three illumination settings: Off (which allows the tubes natural amber glow to be visible), Green or Blue – a new colour option unique to the MC2152.

Sentry Monitor technology monitors the output current and shuts the amplifier off if it ever exceeds safe limits.

On the back are both balanced and unbalanced inputs, along with McIntosh's patented Solid Cinch speaker binding posts.

Finally, there is an input and output for the company's Power Control technology that will automatically turn other connected McIntosh components on and off.

C70 70th Anniversary Vacuum Tube Preamplifier

Partnering the MC2152 is the C70 70th Anniversary Vacuum Tube Preamplifier. The C70 harkens back to yesteryear with all analogue design and a retro look. The glass front panel is inscribed with unique McIntosh 70th Anniversary lettering.

The C70 features one 12AT7 and five 12AX7A vacuum tubes that are visible through a glass panel on the top cover.

Control operations are all via traditional knobs and rocker switches. However, modern LED indicators denote input selection and volume level.

The C70 has seven inputs consisting of two balanced inputs, three unbalanced inputs, and one each of Moving Coil and Moving Magnet phono inputs. For outputs, there are two pairs each of balanced and unbalanced connections.

On the front panel, bass and treble tone controls are included and can be adjusted in 2dB increments via rotary knobs. Rotary knobs are also used to change the impedance and capacitance for the phono inputs. As well as controlling the listening level, the volume knob can also adjust the relative volume balance between the left and right audio channels.

A ¼-inch headphone jack powered by McIntosh's High Drive headphone amplifier is included and features their Headphone Crossfeed Director (HXD) technology. Five rocker switches are used to control the following functions: tone control on/ off; change between mono and stereo mode; HXD on/off; and to turn the independent output 1 and output 2 on/off.

The C70 sits atop a beautiful polished stainless steel chassis and features the timeless McIntosh black glass front panel, illuminated logo, control knobs, and aluminium end caps.

Again, the firm's Power Control technology is included with four ports that can automatically turn other connected McIntosh components on and Data ports are also present and can control essential functions of connected McIntosh source components such as CD Players via the C70's remote control.

McIntosh President Charlie Randall told StereoNET:

We are honoured to be entering our 70th year of fulfilling Mr Mac's vision of bringing world-class home audio equipment to music and audio lovers everywhere. We've been fortunate to be able to do what we love to do for so long. We couldn't have done that without the support of all our customers, dealers and distributors, and I'd like to thank each one of them. And since we have been so fortunate, we are delighted to be able to give back to those in need via a donation to Save the Children, a truly worthwhile charity dedicated to helping children everywhere.

Save the Children Executive Vice President and Chief Operating Officer Carlos Carrazana added:

We are grateful to McIntosh for making us a part of their 70th-anniversary celebration. Next year is also significant for Save the Children as we commemorate our 100th anniversary – a milestone that could not be possible without the support of partnerships like this.
