C70
The C70 70th Anniversary Vacuum Tube Preamplifier harkens back to yesteryear with an all analog design and a retro look. The glass front panel is inscribed with special 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. All control operations
are done via knobs and rocker switches. Modern LED indicators will
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 adjust the impedance and capacitance for the phono inputs. In
addition to controlling the listening level, the volume knob can also
adjust the relative volume balance between the left and right audio
channels. A ¼” headphone jack powered by our High Drive headphone
amplifier is included and features our Headphone Crossfeed Director (HXD®)
technology. HXD brings added dimension to your music in a natural
sounding way but can be turned off depending on your preferences. 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.
MC2152
The MC2152 70th Anniversary Vacuum Tube Amplifier is a 150 Watt
per channel stereo amplifier and features a striking new design to
celebrate McIntosh's seven decades of handcrafting some of the best home
audio equipment the world has ever heard. While its design is new, the
MC2152 incorporates the lessons we’ve learned and the techniques we’ve
invented in McIntosh's 70 years of audio engineering.
The stunning new design of the MC2152 is highlighted by a bead blasted black anodized aluminum chassis accentuated with matte finish carbon fiber 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.
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 color option unique to the MC2152. Our Sentry Monitor™ technology
monitors the output current and shuts the amplifier off if it ever
exceeds safe limits.
