From my Ebay listing:

I bought these 3 yrs. ago and am the 2nd owner. Built by Mr.Had in July of 2014 and sold to me by the original owner after 4 months use. They are perfect in every way. I have 2 other amp systems (Inspire "807" w/ matching pre and a Cary SLI-80) and have decided these are what I'm parting with. Assuming serious buyers will be familiar with Mr. Had and his Inspire line of single ended designed amps and recognize the value of this auction..
