I have a brand new in the box Sherbourn 7/2100a 7 channel amplifier; It has 7 monoblocks housed in 1 chassis, both XLR and RCA inputs, gold plated five-way binding posts, both a 12v and low voltage trigger, and Sherbourns Load Detection System to prevent any shorts or damage to the amplifier. It is IMHO one of the best values out there for 7 channel amplification. I will include the reciept in the purchase, and it was purchased from an authorized dealer. This box has never been opened. I do NOT upcharge for paypal per their regulations. From Sherbourn: The 7/2100A weighs an astounding 115 pounds and features the world’s first seven mono block, seven toroidal transformer amplifier. This brute will output a massive 2.1 kW and comes with two power cords to ensure that you can pull all of the needed power from two outlets, which eliminates the need to install a special 20-amp circuit. Sherbourn uses only the finest components, including fifty-six bi-polar Mosfet transistors and has an over 150,000 microfarad capacitance. The rear panel includes XLR and RCA inputs, gold plated five-way binding posts and a low voltage trigger input. Unique to Sherbourn is our LDS, (Load Detection System) that allows the amp to sample the signal before powering up and will detect if the “load” is within safe parameters.

This is a chance to pick up a new in the box Sherbourn for far below retail.
