Cary C306 Reference Preamplifier

UPDATE: I REMOVE THE AMP FROM MY SYSTEM AND TOOK  NEW  PICTURE. THERE ARE NO SCRATCHES ANYWHERE ON THE AMP. WHAT I THOUGHT WERE SCRATCHES WERE SIMPLY DUST ON THE REAR OF THE AMP. SEE PICTURE! 
I am selling my Cary Audio Design C-306 Reference Preamplifier which I bought 4 years ago. The amplifier works great and is in excellent condition. Included with the amp is the original manual, remote and power cord. I don�t have the original box but it will be carefully package.

The is a great preamplifier, it was part of Cary Designer Series which include the A-306 power amplifier and the CD-306 SACD player.
This is what one reviewer has to say about the C 306:

The C306 preamplifier merges digital computer technology and pure analog discrete circuitry. The C306 has four 18dB analog line gain stages two separate gain stages for each channel. One gain stage amplifies the positive phase (+180 degrees) and the other gain stage amplifies the negative phase (-180 degrees). Two stages for each channel equal the four active line circuits. All signals in the audio path are routed through Class A solid-state devices utilizing both FET inputs and low impedance push-pull bipolar output devices. To control the available gain, stepped 0.1% resistors are employed in a relay-controlled ladder attenuated circuit. This stepped individual resistor control circuit is said to provide the most signal purity.

The front panel display on the C306 is a Noritake vacuum florescent display with a blue lens. This receives and displays the critical control functions from a 32-bit Motorola CPU inside the unit. The CPU stores all user-selected information including volume level of each selected input, phase polarity and the selected balance setting for each channel. The CPU is the brain controlling the stepped attenuation system. The Motorola processor controls all functions of the preamplifier.

On the C306's analog side, there are a total of eight fully regulated power supplies dedicated to each channel's analog circuit as well as multiple power supplies for the alphanumeric, Noritake display, and dual supplies for the Motorola processor. The entire preamplifier is built from precision machined aluminum. All PC boards are multi-sided plated through G-10 glass.

Obviously, the rather complex and thoughtfully engineered C306 preamplifier provides the sonic merits of Cary Audio Design C 306 offer the music lover the ultimate in realistic �they are here� music performance. Nothing in this preamplifier disturbs, nothing gets in the way of the music.

I will ship the amp on the first Friday after payment has been received. I will accept money order or PayPal, buyer add 3% for PayPal.

Good luck!
