Oops, "pass" his test ;-). Warren demands to know what arm (and table) the pickup is going on, who will be doing the mounting and aligning, etc. If he disapproves of your answer, no sale. Weird!
Though I have done the chore numerous times, I told him I might have Brian Berdan (at Audio Elements in Pasadena, CA) do it this time. Brian was trained by his late father, the cartridge/arm/table master Brooks Berdan (ARC's Bill Johnson had Brooks come out to his Winter home in Palm Desert---an hour-and-a-half drive from Brooks' shop in Monrovia, CA---to set up his table), and is one of the handful of best in the country. Warren had heard of neither! Kinda clueless, but he does know the cartridge.
