I'm part of group that is readying two Audio Precision System One Dual
Domain measurement systems for market.

The units have exceptional provenance. They were owned by Stereo Review
Magazine and were the personal tools of Julian Hirsch. They still have
Hachette Publications property stickers on them.

Hachette Filipacchi Media U.S magazine operations, like Ziff Davis, and
indeed Stereo Review, are regrettably no more. We obtained these units from
Hachette as surplus items right before they moved their offices in
Manhattan.

According to http://en.wikipedia.org/wiki/Hachett...cchi_Media_U.S. ,
Hachette's US magazine operations were sold off in May, 2010.

The condition of the equipment is excellent. All of the tests I've run
worked the first time. We have them fully operational and attached to
computers running Windows XP. We believe that we have drivers and I/O cards
that will work with even later versions of Windows. The units are a tiny bit
out of calibration. We intend to run 100% of the diagnostics and have them
entirely nominal before sale.

While not SOTA in terms of distortion residuals, AP S1 systems are still
valuable tools for many current applications due to their excellent
interfaces, good performance, and programmability. We intend to sell them as
turnkey systems - unbox what we send you, plug it in, and go!
