I second the very positive comments that others have made about Maier. Back in 2010, when I was figuring out how best to do my massive ripping project (over 10,000 albums), we had a shootout (Maier was one of the attendees) and I determined the best ADAC was the Pacific Microsonics Model Two. Unfortunately, it was also the one that was not obtainable. I was working with my consultant, Tim Marutani, and he enlisted Maier's help. About three months later, I got the great news, Maier had found two Model Two's sitting at Warner Bros studios. I got one of them and Maier has the other at his Audio Salon. There were only about 150 or so made and they are preciously owned by recording and mastering engineers and studios, with a few in private hands. Thanks to Maier, I have one of them.
Maier's shop, The Audio Salon, in Santa Monica's Bergamot Station, has one of the best acoustically designed listening rooms, a joy to visit. If your significant other is not interested in spending time listening to audio equipment, Bergamot Station has an assortment of very nice art galleries and other shops (not a typical mall atmosphere) to while a way the time.
