With rare exceptions, I buy used components. One of those exceptions occurred recently when I made my first ever purchase of a stand-alone DAC. Having done plenty of research online, I opted for a Denafrips Pontus II, and have thus far been quite happy with it.
However, there were some small (non-mechanical) issues initially, and Alvin Chee, owner of Vineshine Audio in Singapore, worldwide distributor of Denafrips, was extremely helpful. He regularly appears on various forums, including Audiogon, and to help troubleshoot, not directly market his products, and seems to always be available to help customers, or prospective customers, with any questions or issues that they may have.
Like @millercarbon, I also have an honorable mention. While Green Mountain Audio was a relatively small, boutique speaker manufacturer, the late Roy Johnson, owner and designer, was almost unbelievably generous with his time and knowledge. I'd estimate that he spent a good two to three hours on the phone with me before I bought my first pair. I know that I wasn't alone, either, as similar testimonials appeared online now and then. RIP, Roy.
