Many conflicting opinions here... some like Roon, some like Aurender, etcetera. In my case, I spent about $4.4K on a used Aurender N10 (from a well known dealer). The unit had connection issues right from the start and the dealer begrudgingly agreed to have it shipped to Aurender SC, where they replaced the hard drive and ran full diagnostics. The returned unit ran for a few days, then once again, I was unable to connect. I tried trouble shooting with Aurender customer service and eventually gave up, selling for a loss. It could be that my AT&T internet service or modem did not play nice with Aurender, but I have read of others having similar experiences. In Aurenders defense, they do appear to have many satisfied customers.
