Hi @dahodevil, authorized Aurender dealer here. If you can swing it, try to purchase the N150. In addition to the hardware improvements that deliver improved sonic performance, the architecture of the N150 is completely different than that of the older N100H. The newer architecture allows for more modern features, such as being Roon Ready, and other future services that the N100H will never be able to support.
Also, keep in mind that when purchasing used, Aurender warranties are non-transferable, and the N100H has been out on the market long enough such that all of their warranties are expired. Aurender provides amongst the best customer service and support I’ve seen in high end audio, and if you ever get into any hiccups (remember, you are purchasing sophisticated electronics), they never hesitate to help make the experience better.
Happy to answer any more questions, either here on this thread or via private message. Feel free to get in touch if you want to know more about the different models.
Best,
Juan
