Audio Research Reference 160 M monoblock amps (pair)

Selling a black pair of ARC REF 160 M amps in mint condition.  I bought these new from an authorized ARC dealer .  They have been sitting in my dedicated listening room since then.  Very little use due to having other amplifiers.  The hour counter on back says 913 hours.
I would prefer buyer arrange for shipping--preferably freight with these on a pallet just to minimize chance of damage.  I can discuss this with a potential buyer and work something out.
