This is a Reference pre-amp and matching amplifier from pioneer. Especially great for vinyl fans since this preamp come with an excellent phono stage with a switch for MM or MC cartridges. Just the preamp alone sold not long ago on audiogone for just under $600 by itself so here you get a bonus amp with it! What an amp it is as well. The M72 is pioneers longest produced amplifier design and was made for 10 years before being replaced. Why mess with something you got right the first time.
The amp itself sells for anywhere from $200 to $400 from what I have seen out there so its well worth what I am asking for the combo. They are both in great shape with very minor imperfections to be found on them. There are only 2 issues I have found with them.
1) The pre-amp is missing the wooden sides / or the amp however you would prefer it since they are interchangeable between them. It would be very easy to make new wooden sides for both that match and can be even more beautiful then the originals. Its simply a square piece of wood with 2 holes in it so easy enough to make even for the lesser skilled out there. Stain the wood and urethane it and you can have any look you want on them!
2) The original remote control is missing but a replacement non-original remote is included.
I am willing to ship these to you as long as you pay for the shipping or I can deliver up to 100 miles around Atlanta Ga.
The Pioneer C-72 has a total of five audio inputs, and five video inputs, with one video input on the front panel.
Clean ground technology prevents noise on the power line from flowing to the signal ground line, permitting clean sound reproduction.
Relay and electronic signal switching keep the signal route as short as possible. By switching the Direct On/Off function On, the signal bypasses any sound quality adjusting circuitry, giving you the pure, unaffected sound.
When not using video and phono inputs, turn the video power circuit and the phono equalizer power circuit off in order to prevent them from collecting noise during playback of other sources.
The control power supply of the C-72 has its own transformer which is isolated from a second transformer having separate windings supplying the audio and video systems, so there is virtually no interference between them.
All parts used, including the newly developed motor-driven volume control, operational amp IC's, capacitors, resistors, printed circuit board and lead wires, were selected to assure high sound quality.
The recording selector is equipped to handle all audio and video inputs, so you can record from any source while playing another.

Very long production run for this mid-end amplifier made to somewhat bridge the gap between 2-channel audiophilia and 4-channel home-cinema.
The long production was however mainly for the US, not Japan.
Built like few of today's mid-end home-cinema amplifiers, if any, the M-72 holds two large "Pure" transformers, two "Pure" copper-shielded 27,000µF ELNA capacitors made for Pioneer, non-resonant chassis and feet through the use of honeycomb embossing (chassis), added elements (in-feet), damping material sandwich (inside sides), and design (diecast aluminium heatsinks).
As in the C-72 companion, Super Linear Circuit (SLC) cancels the non-linearity of one semi-conductor with the linearity of another and Clean Ground System (CGS) manages to isolate noise from the signal path and said signal path is reduced to minimum lengths (80cm max.) with deported shafts and relays.
Mainly, the M-72 is a 4-channel connection center with one amplifier module able to feed one or two stereo loudspeaker pairs (AMP 1, pairs A and B) and the other, AMP 2, serving as added rear 'speakers feed : pair C.
