These monitors sound amazing, and more importantly, they will tell you the truth.
I was excited to get these, and imagine my suprise when one of the monitors was dead on arrival. Just dead, wouldn't power up. The replacement had a problem with the tweeter, it was not properly aligned with the protective grill, about 1/8" too high. The one that replaced that has scratches on the top of the cabnet where the tweeter is mounted, and on the grill itself. I emailed Adam a week and a half ago, but still have received no response.
When I pay $500.00 for a monitor, I expect it to be properly assembled, and in good working order. I also expect the new monitor to be free from flaws. When I email the manufacturer about questionable quality control issues, I expect a response within a few days, or at least within a week. Hopefully the fourth monitor will be manufactured properly, and with care.
While these really are steller and accurate monitors (they really do sound fantastic), it seems that high quality manufacturing standards and customer satisfaction are not a priority at Adam.
The monitors that I had prior to the Adams were significantly less expensive, were made in China, and arrived in perfect working order without any flaws.
If you have the patience and time to exchange a few monitors before you get a pair that are properly made, then these might be for you. As for me, I don't think that I will be going up the ladder to Adam's more expensive monitors when I'm ready to upgrade. If I can't trust you with $500, why would I trust you with thousands?
