McIntosh MA-6600 [Expired]

no longer for sale

Beautiful, pristine McIntosh MA-6600, integrated solid state amplifier.  This has been very sparingly used during its lifetime.  It comes with original box, packing material, owners manual, and optional FM tuner module that plugs into the back of the amplifier and allows for the selection of FM stations.  This unit was purchased by me approximately 18 months ago and used sparingly.  It sounds beautiful and is being sold only because I am preparing to go overseas for an extended period and rather than let this sit in storage, it is being offered for sale so others can enjoy the beautiful music it makes.
Specifications from the McIntosh owners manual follow.  Note, please, this is a heavy beast.  It weighs almost 100 pounds or 45Kg in the box.  Shipping to anywhere in the 48 states is a flat $100.  Shipping to AK, HI, Canada or elsewhere will be at cost as calculated by UPS or another suitable carrier who will get this beautiful integrated amp to you in the condition it leaves me.
